The patch adds driver support for static/local dcbx mode. In this mode
adapter brings up the dcbx link with locally configured parameters
instead of performing the dcbx negotiation with the peer. The feature
is useful when peer device/switch doesn't support dcbx.

1GbE Intel Wired LAN Driver Updates 2017-04-20
This series contains updates to e1000, e1000e, igb/vf and ixgb.
Tobias Klauser cleans up e1000, ixgb and igbvf from having a local
function or structure for netdev stats.
Bernd Faust fixes an issue for 82579 devices, where the clock frequency
was being incorrectly set for these devices. These devices only support
96MHz, so make sure they are set to use only that.
Yury Kylulin extends the work Jake and Alex did for ixgbe in MAC filter
handling into the igb driver.
Kim Tatt Chuah enables igb to wake up by packet and to read the necessary
Wake Up Status (WUS) and Wake Up Packet Memory (WUPM) registers.

Earlier patch 4493b81bea ("bonding: initialize work-queues during
creation of bond") moved the work-queue initialization from bond_open()
to bond_create(). However this caused the link those are created using
netlink 'create bond option' (ip link add bondX type bond); create the
new trunk without initializing work-queues. Prior to the above mentioned
change, ndo_open was in both paths and things worked correctly. The
consequence is visible in the report shared by Joe Stringer -
I've noticed that this patch breaks bonding within namespaces if
you're not careful to perform device cleanup correctly.
Here's my repro script, you can run on any net-next with this patch
and you'll start seeing some weird behaviour:
ip netns add foo
ip li add veth0 type veth peer name veth0+ netns foo
ip li add veth1 type veth peer name veth1+ netns foo
ip netns exec foo ip li add bond0 type bond
ip netns exec foo ip li set dev veth0+ master bond0
ip netns exec foo ip li set dev veth1+ master bond0
ip netns exec foo ip addr add dev bond0 192.168.0.1/24
ip netns exec foo ip li set dev bond0 up
ip li del dev veth0
ip li del dev veth1
The second to last command segfaults, last command hangs. rtnl is now
permanently locked. It's not a problem if you take bond0 down before
deleting veths, or delete bond0 before deleting veths. If you delete
either end of the veth pair as per above, either inside or outside the
namespace, it hits this problem.
Here's some kernel logs:
[ 1221.801610] bond0: Enslaving veth0+ as an active interface with an up link

Currently driver use phy_start_aneg() in arc_emac_open() to bring
up PHY. But phy_start() function is more appropriate for this purposes.
Besides that it call phy_start_aneg() as part of PHY startup sequence
it also can correctly bring up PHY from error and suspended states.
So the patch replace phy_start_aneg() to phy_start().
Also the patch add call to phy_stop() to arc_emac_stop() to allow
the PHY device to be fully suspended when the interface is unused.

40GbE Intel Wired LAN Driver Updates 2017-04-19
This series contains updates to i40e and i40evf only, most notable being
the addition of trace points for BPF programs.
Tobias Klauser updates i40evf to use net_device stats struct instead
of a local private copy.
Preethi updates the VF driver to not enable receive checksum offload by
default for tunneled packets.
Alex fixes an issue he introduced when he converted the code over to
using the length field to determine if a descriptor was done or not.
Mitch adds the ability to dump additional information on the VFs, which
is not available through 'ip link show' using debugfs.
Scott adds trace points to the drivers so that BPF programs can be
attached for feature testing and verification.
Jingjing adds admin queue functions for Pipeline Personalization Profile
commands.
Jake does most of the heavy lifting in this series, starting with the
a reduction in the scope of the RTNL lock being held while resetting VFs
to allow multiple PFs to reset in a timely manner. Factored out the
direct queue modification so that we are able to re-use the code.
Reduced the wait time for admin queue commands to complete, since we were
waiting a minimum of a millisecond, when in practice the admin queue
command is processed often much faster. Cleaned up code (flag) we never
use. Make the code to resetting all the VFs optimized for parallel
computing instead of the current way is a serialized fashion, to help
reduce the time it takes.

Add functionality for the VF to request up to 3 additional MAC filters.
This is done using existing E1000_VF_SET_MAC_ADDR message, but with
additional message info - E1000_VF_MAC_FILTER_CLR to clear all unicast
MAC filters previously set for this VF and E1000_VF_MAC_FILTER_ADD to
add MAC filter.
Additional filters can be added only in case if administrator did not
set VF MAC explicitly and allowed to change default MAC to the VF.
Due to the limited number of RAR entries reserve at least 3 MAC filters
for the PF.
If SRIOV is supported by the NIC after this change RAR entries starting
from 1 to (RAR MAX ENTRIES - NUM SRIOV VFS) will be used for PF and VF
MAC filters.

commit 5d7daa35b9 ("ixgbe: improve mac filter handling") and Alexander
Duyck commit 0f079d2283 ("ixgbe: Use __dev_uc_sync and __dev_uc_unsync
for unicast addresses") and out-of-tree igb driver add functionality to
manage (add and delete) MAC filters.

After an upgrade to Linux kernel v4.x the hardware timestamps of the
82579 Gigabit Ethernet Controller are different than expected.
The values that are being read are almost four times as big as before
the kernel upgrade.
The difference is that after the upgrade the driver sets the clock
frequency to 25MHz, where before the upgrade it was set to 96MHz. Intel
confirmed that the correct frequency for this network adapter is 96MHz.

PFC error-mask value is not supported by MFW, but this bit could be
set in the pfc bit-map of the operational parameters if remote device
supports it. These operational parameters are used as basis for
populating the dcbx config parameters. User provided configs will be
applied on top of these parameters and then send them to MFW when
requested. Driver need to clear the error-mask bit before sending the
config parameters to MFW.

10GbE Intel Wired LAN Driver Updates 2017-04-18
This series contains updates to mainly ixgbe with only one ixgbevf change.
Usha adds a check to ensure the creation of number of VF's is valid based
on the traffic classes configured, all to avoid transmit hangs.
Joe Perches reduces the use of pr_cont since the output can be interleaved
by other processes.
Tony cleans up the code overwriting the KX4 config, which is configured by
the NVM. Adds a check for MMNGC.MNG_VETO, to resolve an issue where we
were getting a link loss for the BMC when loading the driver.
Don fixes up SGMII x553 config details which were missed in earlier
implementations. Added support for x552 XFI backplane interface support.
Cleaned up an unused define, which was causing confusion on supported
devices.
Emil fixes a link issue on KR parts by making sure the default setting is
set. Refactors the code so that the code for allocating memory for the
list of MAC addresses that the VFs can use into its own function. Made
some code cleans to help readability and ensure notification of SRIOV
being enabled is done upon completion. Fixed an issue where if we failed
to allocate vfinfo in __ixgbe_enable_sriov() the driver would crash with
a NULL pointer dereference.
Philippe Reynes updates ixgbevf to use the new API for
{get|set}_link_ksettings.
Alex increases the headroom allocation when using build_skb() on a
system with 4K pages. Fixed an issue in ixgbe_dump() where we were no
longer clearing the status bit.

This patch is prompted by a static checker warning about a potential
use after free. The concern is that netif_rx_ni() can free "skb" and we
call it twice.
When I look at the commit that added this, it looks like some stray
lines were added accidentally. It doesn't make sense to me that we
would recieve the same data two times. I asked the author but never
recieved a response.
I can't test this code, but I'm pretty sure my patch is correct.

When there is no FID set for a specific packet, the HW will drop it.
However, by default these packets are useful to be delivered to CPU as
it can inspect them and program HW accordingly. So add this trap.
This would only ever happen when port is enslaved to an OVS master.
Otherwise, packets would be dropped during VLAN / STP filtering,
before FID classification.

>From now on, a port can become a slave of OVS master. All vlans
are enabled, STP state is set to "forwarding". It is up to the OVS
userspace daemon to setup the flows either in kernel or in HW using TC
flower offload.
