[PATCH russell-kings-net-queue v2 3/3] net: phylink: don't fail attaching phy on 1000base-x/2500base-x mode

[Marek Behún]

Some SFPs may contain an internal PHY which may in some cases want to
connect with the host interface in 1000base-x/2500base-x mode.
Do not fail if such PHY is being attached in one of these PHY interface
modes.
