100GbE Intel Wired LAN Driver Updates 2020-02-19
This series contains updates to the ice driver only.
Avinash adds input validation for software DCB configurations received
via lldptool or pcap to ensure bad bandwidth inputs are not inputted
which could cause the loss of link.
Paul update the malicious driver detection event messages to rate limit
once per second and to include the total number of receive|transmit MDD
event count.
Dan updates how TCAM entries are managed to ensure when overriding
pre-existing TCAM entries, properly delete the existing entry and remove
it from the change/update list.
Brett ensures we clear the relevant values in the QRXFLXP_CNTXT register
for VF queues to ensure the receive queue data is not stale.
Avinash adds required DCBNL operations for configuring ETS in software
DCB CEE mode. Also added code to detect if DCB is in IEEE or CEE mode
to properly report what mode we are in.
Dave fixes the driver to properly report the current maximum TC, not the
maximum allowed number of TCs.
Krzysztof adds support for AF_XDP feature in the ice driver.
Jake increases the maximum time that the driver will wait for a PR reset
to account for possibility of a slightly longer than expected PD reset.
Jesse fixes a number of strings which did not have line feeds, so add
line feeds so that messages do not rum together, creating a jumbled
mess.
Bruce adds support for additional E810 and E823 device ids. Also
updated the product name change for E822 devices.

The description says 'If unsure, say N.' but
the module is built as M by default (once
the dependencies are satisfied).
When the module is selected (Y or M), it enables
NETFILTER_FAMILY_BRIDGE and SKB_EXTENSIONS
which alter kernel internal structures.
We (Android Studio Emulator) currently do not
use this module and think this it is more consistent
to have it disabled by default as opposite to
disabling it explicitly to prevent enabling
NETFILTER_FAMILY_BRIDGE and SKB_EXTENSIONS.

at91ether_init was handling the phy mode and speed but since the switch to

Add new capability to differentiate between EMAC and the other versions of

Some code pathes rely on preempt_disable() to prevent migration on a non RT
enabled kernel. These preempt_disable/enable() pairs are substituted by
migrate_disable/enable() pairs or other forms of RT specific protection. On
RT these protections prevent migration but not preemption. Obviously a
cant_sleep() check in such a section will trigger on RT because preemption
is not disabled.
Provide a cant_migrate() macro which maps to cant_sleep() on a non RT
kernel and an empty placeholder for RT for now. The placeholder will be
changed to a proper debug check along with the RT specific migration
protection mechanism.

Code which solely needs to prevent migration of a task uses
preempt_disable()/enable() pairs. This is the only reliable way to do so
as setting the task affinity to a single CPU can be undone by a
setaffinity operation from a different task/process.
RT provides a seperate migrate_disable/enable() mechanism which does not
disable preemption to achieve the semantic requirements of a (almost) fully
preemptible kernel.
As it is unclear from looking at a given code path whether the intention is
to disable preemption or migration, introduce migrate_disable/enable()
inline functions which can be used to annotate code which merely needs to
disable migration. Map them to preempt_disable/enable() for now. The RT
substitution will be provided later.
Code which is annotated that way documents that it has no requirement to
protect against reentrancy of a preempting task. Either this is not
required at all or the call sites are already serialized by other means.

If BPF program is using BTF-defined maps, BTF is required only for
libbpf itself to process map definitions. If after that BTF fails to
be loaded into kernel (e.g., if it doesn't support BTF at all), this
shouldn't prevent valid BPF program from loading. Existing
retry-without-BTF logic for creating maps will succeed to create such
maps without any problems. So, presence of .maps section shouldn't make
BTF required for kernel. Update the check accordingly.
Validated by ensuring simple BPF program with BTF-defined maps is still
loaded on old kernel without BTF support and map is correctly parsed and
created.

EBUSY is used because vnicc feature and bridgeport feature are mutually

Functions starting with __ usually indicate those which are exported,
but should not be called directly. Update some of those declared in the
API and make it more readable.
page_pool_unmap_page() and page_pool_release_page() were doing
exactly the same thing calling __page_pool_clean_page(). Let's
rename __page_pool_clean_page() to page_pool_release_page() and
export it in order to show up on perf logs and get rid of
page_pool_unmap_page().
Finally rename __page_pool_put_page() to page_pool_put_page() since we
can now directly call it from drivers and rename the existing
page_pool_put_page() to page_pool_put_full_page() since they do the same
thing but the latter is trying to sync the full DMA area.
This patch also updates netsec, mvneta and stmmac drivers which use
those functions.

mlxsw: Preparation for RTNL removal
The driver currently acquires RTNL in its route insertion path, which
contributes to very large control plane latencies. This patch set
prepares mlxsw for RTNL removal from its route insertion path in a
follow-up patch set.
Patches #1-#2 protect shared resources - KVDL and counter pool - with
their own locks. All allocations of these resources are currently
performed under RTNL, so no locks were required.
Patches #3-#7 ensure that updates to mirroring sessions only take place
in case there are active mirroring sessions. This allows us to avoid
taking RTNL when it is unnecessary, as updating of the mirroring
sessions must be performed under RTNL for the time being.
Patches #8-#10 replace the use of APIs that assume that RTNL is taken
with their RCU counterparts. Specifically, patches #8 and #9 replace
__in_dev_get_rtnl() with __in_dev_get_rcu() under RCU read-side critical
section. Patch #10 replaces __dev_get_by_index() with
dev_get_by_index_rcu().
Patches #11-#15 perform small adjustments in the code to make it easier
to later introduce a router lock instead of relying on RTNL.

The device supports a single VTEP whose configuration is shared between
all VXLAN tunnels.
While the shared configuration is cleared upon the destruction of the
last tunnel - in mlxsw_sp_nve_tunnel_fini() - it is set in
mlxsw_sp_nve_fid_enable(), after calling mlxsw_sp_nve_tunnel_init().
Make tunnel initialization and destruction symmetric and set the
configuration in mlxsw_sp_nve_tunnel_init().

IPv6 addresses are deleted in an atomic context, so the driver defers
the potential teardown of the associated router interface (RIF) to a
work item that takes RTNL.
The RIF is only destroyed if the associated netdev does not have any IP
addresses (both IPv4 and IPv6). The IPv4 device ('struct in_device') is
currently fetched via __in_dev_get_rtnl() which assumes RTNL is taken.
Since RTNL is going to be removed, convert it to use __in_dev_get_rcu()
from an RCU read-side critical section.
Note that the IPv6 device ('struct inet6_dev') is fetched via
__in6_dev_get(), which does not require RTNL.

The driver updates its mirroring agents whenever it receives a
notification about an event that can affect these. For example, the
addition of a route might require the driver to change the egress port
of an ERSPAN session.
Currently, RTNL needs to be held when these agents are updates, so the
driver either:
1. Calls directly into the mirroring code, in case RTNL is held
2. Schedules a work item that will take RTNL and call into the mirroring
code
Simplify this by having the mirroring code schedule the work item for
the update instead of requiring callers to schedule a work item
themselves.
The conversion of the callers will be done in the next patch to make
review easier.
This will later allow us to remove RTNL from different parts of the
driver. It will also allow us to only schedule the work item in case
there are active mirroring agents, which is information private to the
mirroring code.

commit 5f2958052c ("igc: Add basic skeleton for PTP") added basic
support for PTP, what's missing is support for suspending.
Legacy power management has been added. Now we can add
the suspend method to the igc_shutdown.
By cleaning the runtime storage for timestamp this avoids a possible
invalid memory access when the system comes back from suspend state.

Intel Wired LAN Driver Updates 2020-02-19
This series contains fixes to the ice driver.
Brett fixes an issue where if a user sets an odd [tx|rx]-usecs value
through ethtool, the request is denied because the hardware is set to
have an ITR with 2us granularity. Also fix an issue where the VF has
not been completely removed/reset after being unbound from the host
driver, so resolve this by waiting for the VF remove/reset process to
happen before checking if the VF is disabled.
Michal fixes an issue, where when the user changes flow control via
ethtool, the OS is told the link is going down when that may not be the
case. Before the fix, the only way to get out of this state was to take
the interface down and up again.

net: phy: Better support for BCM54810
This patch series updates the broadcom PHY driver to better support the
BCM54810 and allow it to make use of the exiting
bcm54xx_adjust_rxrefclk() as well as fix suspend/resume for it.
Changes in v2:
- added Reviewed-by tags from Andrew for patches #1 and #3
- expanded commit message in #2 to explain the change
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The BCM54810 PHY can use the standard BMCR Power down suspend, but needs
a custom resume routine which first clear the Power down bit, and then
re-initializes the PHY. While in low-power mode, the PHY only accepts
writes to the BMCR register. The datasheet clearly says it:
Reads or writes to any MII register other than MII Control register
(address 00h) while the device is in the standby power-down mode may
cause unpredictable results.
