From: Aviv Heller Date: Tue, 18 Dec 2018 17:03:27 +0000 (+0200) Subject: net/mlx5: Fix LAG requirement when CONFIG_MLX5_ESWITCH is off X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a64917446eafc7212e962561622d697fce04e9a6;p=openwrt%2Fstaging%2Fblogic.git net/mlx5: Fix LAG requirement when CONFIG_MLX5_ESWITCH is off If CONFIG_MLX5_ESWITCH is not defined, test for SR-IOV being disabled, instead of calling e-switch LAG prereq routine. Since LAG with SRIOV is allowed only when switchdev mode is on.
