In addition we added VxLAN support and introduced a patch
that modifies the driver to report checksum complete in RX path
for all IP (tunneled and non-tunneled) traffic which is non HW LRO.

This series is applied on top of the latest mlx5_ifc and NDO fixes
we sent to the net tree:
net/mlx5e: Use static constant netdevice ndos
net/mlx5e: Remove select queue ndo initialization
net/mlx5: Use offset based reserved field names in the IFC header file

The QoS patches depend on the IFC change since they expose new fields in
the driver/firmware API. Both QoS and VxLAN patches depend on the NDO changes,
since they add new ndo entries.

Changes from V1:
- Fixed the S.O.B from "Matt" to "Matthew" to be aligned with the committer title.
- Don't populate VxLAN/dcbnl ndos for virtual functions.
- Addressed John comment on mlx5_setup_tc to be aligned with latest API changes.
- Added device ETS capability check prior query/modify ets configuration.
- Call mlx5e_dcbnl_ieee_setets_core at the end of mlx5e_create_netdev and don't
fail netdev creation in case it failed or ETS was not supported.

The series where applied on top of: ("5270c4dade09 Merge branch 'vxlan-cleanups'") +

Added en_dcbnl.c which implements the set/get DCBNL IEEE ETS,
set/get dcbx and registers the mlx5e dcbnl ops.

We still use the kernel's default TXQ selection method to select the

the TXQ inside the channel based on VLAN priority.

Vivien Didelot says:

====================
net: dsa: pass bridge device to drivers

This patchset simplifies the DSA layer.

A switch may support multiple bridges with the same hardware VLAN. Thus a check
such as dsa_bridge_check_vlan_range must be moved from the DSA layer to the
concerned driver.

The first purpose of this patchset is to help moving this check to the
mv88e6xxx driver, which is the only one affected at the moment.

To do that, pass directly the bridge net_device structure down to the DSA
drivers, instead of calculating a bitmask of bridge members.

The second purpose is to prepare the replacement of the complex
port_vlan_getnext approach. A second patchset is ready to follow, implementing
port_vlan_dump and thus simplifying the DSA slave code one more time.

Due to HW design, some of the memories are wide-bus and access to those
needs to be sequentialized on a per-HW-block level; Read/write to a

net: ethernet: davicom: fix devicetree irq resource

The dm9000 driver doesn't work in at least one device-tree
configuration, spitting an error message on irq resource :
[    1.062495] dm9000 8000000.ethernet: insufficient resources
[    1.068439] dm9000 8000000.ethernet: not found (-2).
[    1.073451] dm9000: probe of 8000000.ethernet failed with error -2

The reason behind is that the interrupt might be provided by a gpio
controller, not probed when dm9000 is probed, and needing the probe
deferral mechanism to apply.

Currently, the interrupt is directly taken from resources. This patch
changes this to use the more generic platform_get_irq(), which handles
the deferral.

Moreover, since commit Fixes: 7085a7401ba5 ("drivers: platform: parse
IRQ flags from resources"), the interrupt trigger flags are honored in
platform_get_irq(), so remove the needless code in dm9000.
