Subject: net/mlx5: E-Switch, Move representors definition to a global scope
Patch-mainline: v4.17-rc1
Git-commit: 57cbd893c4c575a24594fa6c0835247506ce26e2
References: bsc#1103990 FATE#326006
In preparation for IB representors, move representors structs to a global
scope, also expose functions needed for registration, unregistration,
eswitch mode and creating a flow rule to direct traffic from SQs to the
right VF.
