From 1e59b32e45e47c8ea5455182286ba010bfa87813 Mon Sep 17 00:00:00 2001 From: Dmytro Linkin Date: Tue, 21 Sep 2021 15:47:33 +0300 Subject: [PATCH] net/mlx5: E-switch, Respect BW share of the new group To enable transmit schduler on vport FW require non-zero configuration for vport's TSAR. If vport added to the group which has configured BW share value and TX rate values of the vport are zero, then scheduler wouldn't be enabled on this vport. Fix that by calling BW normalization if BW share of the new group is configured.
