Title:
TC filters are broken on Mellanox after upstream stable updates
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Bionic:
Fix Committed
Bug description:
[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):
