From 9deb2241f19f26800e3b4c6bf49c4db992192bf0 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Thu, 22 Sep 2016 20:01:42 +0300 Subject: [PATCH] net/mlx5: E-Switch, Set the vport when registering the uplink rep Set the vport value in the PF entry to be that of the uplink so we can use it blindly over the tc / eswitch offload code without translating it each time we deal with the uplink representor.
