Merge branch 'mlx5-updates-2021-01-26'
Saeed Mahameed says:
====================
mlx5 devlink traps support
Add support for devlink traps [1] reporting in mlx5,
mlx5 will also report/trap packets filtered due to dest mac steering miss
The first patch in the series defines the new DMAC trap type in devlink
for this purpose.
Other patches in the series are mlx5 only and they gradually traps support.
Supported traps:
DMAC: Drops due to destination MAC not configured in the MAC table
VLAN: Drops due to vlan not configured in the vlan table
Design note:
devlink instance is managed by the low level mlx5 core layer, mlx5 core will
serve as an abstraction layer for trap reporting, since we might have multiple
mlx5 interfaces who might want to report traps on the same device.
