[SRU][Bionic][PATCH 0/5] TC filters are broken on Mellanox after upstream stable updates (LP: #1842502)

[Juerg Haefliger]

[Impact]

Mellanox TC filters don't work for some key rules after the Bionic 4.15 stable patchset 2019-07-12 update (LP: #1836426). The offending commit is ("net/mlx5e: Set vlan masks for all offloaded TC rules").

This causes fatal network connectivity issues for projects that use the Mellanox ConnectX 5 NIC.

[Test Case]

TBD.

[Fix]

Backport the following upstream commit (which fixes the offending commit) and its prerequisites:
d3a80bb5a3ea ("net/mlx5e: Don't match on vlan non-existence if ethertype is wildcarded")

[Regression Potential]

Low. Changes are isolated and limited to the mlx5_core driver and all commits are in upstream stable v4.19.y.

[Original description]

The following upstream fix was missing from the latest upstream stable update (LP: # and LP1839376: #1839213):

  net/mlx5e: Properly order min inline mode setup while parsing TC
    matches
  net/mlx5e: Get the required HW match level while parsing TC flow
    matches
  net/mlx5e: Always use the match level enum when parsing TC rule match
  net/mlx5e: Don't match on vlan non-existence if ethertype is
    wildcarded
