Subject: net/mlx5e: Provide explicit directive if to create inner indirect
tirs
Patch-mainline: v4.20-rc1
Git-commit: 46dc933cee82c8fd18f5fb8dfa10aceb7a29d5ab
References: bsc#1103990 FATE#326006
Change the driver functions that deal with creating indirect tirs
to get a flag telling if inner ttc is desired.
A pre-step for enabling rss on the vport representors, where
inner ttc is not needed.
