From 5ae5162066d8e59e365678a9e76fc4d8f6b78d40 Mon Sep 17 00:00:00 2001 From: Bodong Wang Date: Fri, 14 Dec 2018 09:33:22 -0600 Subject: net/mlx5: E-Switch, Assign a different position for uplink rep and vport In offloads mode, the current implementation puts the uplink representor at index zero of the vport reps array. It is not "natural" to place it at index 0 since we want to put the representor for vport 0 at index 0 with the introduction of SmartNIC. A separate patch will handle the case whether a rep is needed for vport 0 (PF vport). So, we want to have a different placeholder for uplink vport and representor. It was placed at the end of vport and rep array. Since vport number can no longer act as an index into the vport or representors arrays, use functions to map vport numbers to indices when accessing the vports or representors arrays, and vice versa.
