Subject: net/mlx5: E-Switch, Provide flow dest when creating vport rx rule
Patch-mainline: v4.20-rc1
Git-commit: c966f7d55d00ece53742c4595607402c1d9384a6
References: bsc#1103990 FATE#326006

Currently the destination for the representor e-switch rx rule is
a TIR number. Towards changing that to potentially be a flow table,
as part of enabling RSS for representors, modify the signature of
the related e-switch API to get a flow destination.
