From 41124fa64d4b298b82266b7ddbefc43540b77b44 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 12 Sep 2018 01:53:14 +0200 Subject: net: ethernet: Add helper to remove a supported link mode Some MAC hardware cannot support a subset of link modes. e.g. often 1Gbps Full duplex is supported, but Half duplex is not. Add a helper to remove such a link mode. Signed-off-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S.
