From 1876749da87500c7228f91398e04291389a18634 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 22 May 2017 10:59:34 -0700 Subject: [PATCH] nfp: refresh port state before reporting autonegotiation State of autonegotiation may have changed but is not yet refreshed. Make sure ethtool respects the NFP_PORT_CHANGED flag when looking at autoneg. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Signed-off-by: David S.
