From: Saeed Mahameed Date: Thu, 18 Aug 2016 18:09:02 +0000 (+0300) Subject: net/mlx5e: Set port MTU on netdev creation rather on open X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=13f9bba7cd4f1665e4091143950a54e3f2984b07;p=openwrt%2Fstaging%2Fblogic.git net/mlx5e: Set port MTU on netdev creation rather on open Port mtu shouldn't be written to hardware on every single interface open. Here we set it only when needed, on change_mtu and netdevice creation. Signed-off-by: Saeed Mahameed Signed-off-by: David S.
