This causes problems on the 88E6185/88E6097 where the link partner won't see link link state changes because we're forcing the link. To address this introduce a new device specific op port_sync_link() and push the logic from mv88e6xxx_mac_link_up() into that. Provide an implementation for the 88E6185 like devices which doesn't force the link. Signed-off-by: Chris Packham --- Changes in v4: - Introduce new device op - Remove review from Andrew as things have changed a lot Changes in v3: - None Changes in v2: - Add review from Andrew
