From a4b97ab4211fd0cf1011623c79fe2204dc023b96 Mon Sep 17 00:00:00 2001 From: Mark Bloch Date: Thu, 7 Dec 2017 21:25:57 +0000 Subject: net/mlx5: E-Switch, Create generic header struct to be used by representors Now that we don't store type dependent data in struct mlx5_eswitch_rep we can create a generic interface, and representor type. struct mlx5_eswitch_rep will store an array of interfaces, each interface is used by a different representor type. Once we moved to a more generic interface, rdma driver representors can be added and utilize the same mechanism as the Ethernet driver representors use.
