Subject: net/mlx5: Lag, set match mask according to the traffic type bitmap
Patch-mainline: v5.16-rc1
Git-commit: e465550b38edd71e233520d01b2d5db91d0ae077
References: jsc#SLE-19253
Set the related bits in the match definer mask according to the
TT mapping.
This mask will be used to create the match definers.
