From c6a5011bec0962cfddcce48065e29c65e9a6ec18 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Mon, 22 Mar 2021 17:58:44 +0200 Subject: [PATCH] mlxsw: spectrum_router: Only provide MAC address for valid nexthops The helper returns the MAC address associated with the nexthop. It is only valid when the nexthop forwards packets and when it is an Ethernet nexthop. Reflect this in the checks the helper is performing. This is not an issue because the sole caller of the function only invokes it for such nexthops. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S.
