From 3c1bcc8614db10803f1f57ef0295363917448cb2 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 10 Nov 2018 23:43:33 +0100 Subject: net: ethernet: Convert phydev advertize and supported from u32 to link mode There are a few MAC/PHYs combinations which now support > 1Gbps. These may need to make use of link modes with bits > 31. Thus their supported PHY features or advertised features cannot be implemented using the current bitmap in a u32. Convert to using a linkmode bitmap, which can support all the currently devices link modes, and is future proof as more modes are added. Signed-off-by: Andrew Lunn Signed-off-by: David S.
