From a6589155ec9847918e00e7279b8aa6d4c272bea7 Mon Sep 17 00:00:00 2001 From: Vlad Buslov vladbu@nvidia.com Date: Mon, 18 Apr 2022 17:32:54 +0300 Subject: [PATCH] net/mlx5e: Lag, Fix fib_info pointer assignment
Referenced change incorrectly sets single path fib_info even when LAG is not active. Fix it by moving call to mlx5_lag_fib_set() into conditional that verifies LAG state.
