The patch fixes the computation of RXQs being used by the PPv2 driver,
which is set depending on the PPv2 engine version and the queue mode
used. There are three cases:
- PPv2.1: 1 RXQ per CPU.
- PPV2.2 with MVPP2_QDIST_MULTI_MODE: 1 RXQ per CPU.
- PPv2.2 with MVPP2_QDIST_SINGLE_MODE: 1 RXQ is shared between the CPUs.
The PPv2 engine supports a maximum of 32 queues per port. This patch
adds a check so that we do not overstep this maximum.
It appeared the calculation was broken for PPv2.1 engines since
f8c6ba8424, as PPv2.1 ports ended up with a single RXQ while they
needed 4. This patch fixes it.

driver (88E6390, port 9 in SGMII mode), consisting of alternating
link-up / link-down interrupts. Analysis showed that the driver
wanted to set a cmode that was set already. But so far
mv88e6390x_port_set_cmode() doesn't check this and powers down
SERDES, what causes the link to break, and eventually results in
the described interrupt storm.
Fix this by checking whether the cmode actually changes. We want
that the very first call to mv88e6390x_port_set_cmode() always
configures the registers, therefore initialize port.cmode with
a value that is different from any supported cmode value.
We have to take care that we only init the ports cmode once
chip->info->num_ports is set.
v2:
- add small helper and init the number of actual ports only

As part of creating the tunnel headers while offloading TC encap rules,
we resolve the route and neighbour in order to get the source /
destination mac.
Since the way we offload multipath route is by having two HW rules,
one per uplink port, doing naive route lookup might get us a "wrong"
routing path which goes through the peer uplink and this will get us
eventually to create a wrong L2 header for the tunnel.
To avoid that, we use a device hint to get the correct route.

In a similar manner to uplink/VF LAG, under multipath we add encap peer
rule on the second port as well.
However, unlike the LAG case, we do want to allow failure for adding
one of the rules. This happens due to using a routing hint while doing
the route lookup when one path (next hop device) is down.
Introduce a new flag to indicate that route lookup failed for encap
flow. Note that a flow may still not be offloaded to hw due to missing
neighbour, in that case, the neigh update event will take care of it.

To support multipath offload we are going to track SW multipath route
and related nexthops. To do that we register to FIB notifier and handle
the route and next-hops events and reflect that as port affinity to HW.
When there is a new multipath route entry that all next-hops are the
ports of an HCA we will activate LAG in HW.
Egress wise, we use HW LAG as the means to emulate multipath on current
HW which doesn't support port selection based on xmit hash. In the
presence of multiple VFs which use multiple SQs (send queues) this
yields fairly good distribution.
HA wise, HW LAG buys us the ability for a given RQ (receive queue) to
receive traffic from both ports and for SQs to migrate xmitting over
the active port if their base port fails.
When the route entry is being updated to single path we will update
the HW port affinity to use that port only.
If a next-hop becomes dead we update the HW port affinity to the living
port.
When all next-hops are alive again we reset the affinity to default.
Due to FW/HW limitations, when a route is deleted we are not disabling
the HW LAG since doing so will not allow us to enable it again while
VFs are bounded. Typically this is just a temporary state when a
routing daemon removes dead routes and later adds them back as needed.

When mode is to be changed in mvneta_mac_config, first power the comphy
off, then call mvneta_comphy_init (which sets the mode to new one).

Upon setting the cmode on 6390 and 6390X, the associated serdes

Both 6390X and 6390 share code to do so, but it currently uses the 6390

This call will fail silently on 6390X when trying so set a 10G interface
such as XAUI or RXAUI, since mv88e6390_serdes_power() internally grabs
the lane number based on modes supported by the 6390, and returns 0 when
getting -ENODEV as a lane number.
Using mv88e6390x_serdes_power() should be safe here, since we explicitly
rule-out all ports but the 9 and 10, and because modes supported by 6390
ports 9 and 10 are a subset of those supported on 6390X.

Currently, rx_duration for each peer is not getting populated in
fw_stats debugfs entry for WCN3990.
WCN3990 firmware sends rx duration for each peer as part of
peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats,
firmware expects host to send fw_stats_req_mask with flag
WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD.
Send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in
WMI_REQUEST_STATS_CMD and parse the peer_extd_stats in
WMI_UPDATE_STATS_EVENT to populate the rx_duration of each peer
in fw_stats debugfs entry.
Currently the driver handles 32-bit rx_duration, but the rx_duration
for WCN3990 can be upto 63 bit. The firmware sends rx_duration split
into two 32-bit fields, with the upper 32-bits being valid only if its
MSB is set. This change handles the 63-bit rx_duration obtained from
WCN3990 and maintain the backward compatibility.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(struct boo) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

With Micrel KSZ8061 PHY, the link may occasionally not come up after
Ethernet cable connect. The vendor's (Microchip, former Micrel) errata
sheet 80000688A.pdf descripes the problem and possible workarounds in
detail, see below.
The batch implements workaround 1, which permanently fixes the issue.
DESCRIPTION
Link-up may not occur properly when the Ethernet cable is initially
connected. This issue occurs more commonly when the cable is connected
slowly, but it may occur any time a cable is connected. This issue occurs
in the auto-negotiation circuit, and will not occur if auto-negotiation
is disabled (which requires that the two link partners be set to the
same speed and duplex).
END USER IMPLICATIONS
When this issue occurs, link is not established. Subsequent cable
plug/unplaug cycle will not correct the issue.
WORk AROUND
There are four approaches to work around this issue:
1. This issue can be prevented by setting bit 15 in MMD device address 1,
register 2, prior to connecting the cable or prior to setting the
Restart Auto-negotiation bit in register 0h. The MMD registers are
accessed via the indirect access registers Dh and Eh, or via the Micrel
EthUtil utility as shown here:
. if using the EthUtil utility (usually with a Micrel KSZ8061
Evaluation Board), type the following commands:
> address 1
> mmd 1
> iw 2 b61a
. Alternatively, write the following registers to write to the
indirect MMD register:
Write register Dh, data 0001h
Write register Eh, data 0002h
Write register Dh, data 4001h
Write register Eh, data B61Ah
2. The issue can be avoided by disabling auto-negotiation in the KSZ8061,
either by the strapping option, or by clearing bit 12 in register 0h.
Care must be taken to ensure that the KSZ8061 and the link partner
will link with the same speed and duplex. Note that the KSZ8061
defaults to full-duplex when auto-negotiation is off, but other
devices may default to half-duplex in the event of failed
auto-negotiation.
3. The issue can be avoided by connecting the cable prior to powering-up
or resetting the KSZ8061, and leaving it plugged in thereafter.
4. If the above measures are not taken and the problem occurs, link can
be recovered by setting the Restart Auto-Negotiation bit in
register 0h, or by resetting or power cycling the device. Reset may
be either hardware reset or software reset (register 0h, bit 15).
PLAN
This errata will not be corrected in the future revision.

There have been reports of oversize UDP packets being sent to the
driver to be transmitted, causing error conditions. The issue is
likely caused by the dst of the SKB switching between 'lo' with
64K MTU and the hardware device with a smaller MTU. Patches are
being proposed by Mahesh Bandewar <maheshb@google.com> to fix the
issue.
In the meantime, add a quick length check in the driver to prevent
the error. The driver uses the TX packet size as index to look up an
array to setup the TX BD. The array is large enough to support all MTU
sizes supported by the driver. The oversize TX packet causes the
driver to index beyond the array and put garbage values into the
TX BD. Add a simple check to prevent this.

When the driver receives the tx completion of the

descriptors with 64-bit address.
Currently during handling the tx completion of the

using ce_desc for 32-bit targets. This will lead to clearing
of memory at incorrect offset if DMA MASK is set to greater

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable alloc_size is not necessary, hence
it is removed.

100GbE Intel Wired LAN Driver Updates 2019-02-22
This series contains updates to the ice driver only.
Bruce adds the __always_unused attribute to a parameter to avoid
compiler warnings when using -Wunused-parameter. Fixed unnecessary
type-casting and the use of sizeof(). Fix the allocation of structs
that have become memory hogs, so allocate them in heaps and fix all the
associated references. Fixed the "possible" numeric overflow issues
that were caught with static analysis.
Maciej fixes the maximum MTU calculation by taking into account double
VLAN tagging amd ensure that the operations are done in the correct
order.
Victor fixes the supported node calculation, where we were not taking
into account if there is space to add the new VSI or intermediate node
above that layer, then it is not required to continue the calculation.
Added a check for a leaf node presence for a given VSI, which is needed
before removing a VSI.
Jake fixes an issue where the VSI list is shared, so simply removing a
VSI from the list will cause issues for the other users who reference
the list. Since we also free the memory, this could lead to
segmentation faults.
Brett fixes an issue where driver unload could cause a system reboot
when intel_iommu=on parameter is set. The issue is that we are not
clearing the CAUSE_ENA bit for the appropriate control queues register
when freeing the miscellaneous interrupt vector.
Mitch is so kind, he prevented spamming the VF with link messages when
the link status really has not changed. Updates the driver to use the
absolute vector ID and not the per-PF vector ID for the VF MSIx vector
allocation.
Lukasz fixes the ethtool pause parameter for the ice driver, which was
originally based off the link status but is now based off the PHY
configuration. This is to resolve an issue where pause parameters could
be set while link was down.
Jesse updates the string that reports statistics so the string does not
get modified at runtime and cause reports of string truncation.

On older devices like X710 and X722, the VF's ARQLEN register is cleared
on reset, so the VF driver uses that register to detect an unannounced
reset. Unfortunately, on devices controlled by ice, this register is NOT
cleared on reset. This causes the VF to miss resets, and even on
properly-announced resets, the VF driver complains that it didn't see
the reset.
To fix this, we'll do it in software. When we handle a VF reset (whether
triggered by software or VFLR), clear this register after the HW reset
is complete.

Currently if the kernel has the intel_iommu=on parameter set, on some
platforms removing the driver causes a system reboot. In initialization
we associate the control queue interrupts with the pf->hw_oicr_idx and
enable the interrupts by setting the CAUSE_ENA bit. The problem comes
on teardown because we are not clearing the CAUSE_ENA bit for the
control queues, but the vector at pf->hw_oicr_idx (miscellaneous
interrupt vector) gets disabled.
Fix this by clearing the CAUSE_ENA bit in the appropriate control queue
registers on when freeing the miscellaneous interrupt vector. Also,
move the call to ice_free_irq_msix_misc() to after ice_deinit_sw() in
ice_remove() because ice_deinit_sw() makes an AQ call, but
ice_free_irq_msix_misc() disables the miscellaneous vector and it's
associated interrupts.
Also, create two small helper functions to enable and disable the
control queue interrupts respectively.

When adding multiple VLANs to the same VSI, the ice_add_vlan code will
share the VSI list, so as not to create multiple unnecessary VSI lists.
Consider the following flow
ice_add_vlan(hw, <VSI 0 VID 7, VSI 0 VID 8, VSI 0 VID 9>)
Where we add three VLAN filters for VIDs 7, 8, and 9, all for VSI 0.
The ice_add_vlan will create a single vsi_list and share it among all
the filters.
Later, if we try to remove a VLAN,
ice_remove_vlan(hw, <VSI 0 VID 7>)
Then the removal code will update the vsi_list and remove VSI 0 from it.
But, since the vsi_list is shared, this breaks the list for the other
users who reference it. We actually even free the VSI list memory, and
may result in segmentation faults.
This is due to the way that VLAN rule share VSI lists with reference
counts, and is caused because we call ice_rem_update_vsi_list even when
the ref_cnt is greater than one.
To fix this, handle the case where ref_cnt is greater than one
separately. In this case, we need to remove the associated rule without
modifying the vsi_list, since it is currently being referenced by
another rule. Instead, we just need to decrement the VSI list ref_cnt.
The case for handling sharing of VSI lists with multiple VSIs is not
currently supported by this code. No such rules will be created today,
and this code will require changes if/when such code is added.

With the switch to phy_resolve_aneg_linkmode() we don't read from the
chip any longer what is advertised but use phydev->advertising directly.
For a fixed phy however this bitmap is empty so far, what results in
no common mode being found. This breaks DSA. Fix this by advertising
everything that is supported. For a normal phy this done by phy_probe().

For MR ACL profile is does not make sense to do periodical rehashes, as
there is only one mask in use during the whole vregion lifetime.
Therefore periodical work is scheduled but the rehash never happens.
So allow to enable/disable rehash for the whole group, which is added
per-profile. Disable rehashing for MR profile.
Addition to the vregion list is done only in case the rehash is enable
on the particular vregion. Also, the addition is moved after delayed
work init to avoid schedule of uninitialized work
from vregion_rehash_intrvl_set(). Symmetrically, deletion from
the list is done before canceling the delayed work so it is
not scheduled by vregion_rehash_intrvl_set() again.

whether or not we should read register (1.21) "2.52/5G PMA Extended

After testing on several variants of PHYS of this family, it appears
that bit 14 in (1.11) isn't always set when it should be.
PHYs 88X3310 (on MacchiatoBin) and 88E2010 do support 2.5G and 5GBASET,
but don't have 1.11.14 set. Their register 1.21 is filled with the
