** Description changed:
+ [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):
