Subject: [PATCH net-next 2/9] net/mlx5: E-Switch, Set the vport when registering the uplink rep
From: Or Gerlitz <ogerlitz@...lanox.com>
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.
