[PATCH net-next 3/5] net/mlx5: Remove redundant bw_share minimal value assignment
Posted by Tariq Toukan 2 weeks ago
From: Carolina Jubran <cjubran@nvidia.com>

Remove unnecessary logic that sets bw_share to minimal value, when
parent has bw_share configured but nodes don't have min_rate.

This check is redundant because the parent bandwidth acts as the upper
bound regardless, and the firmware always enforces the topmost
bandwidth constraint.
