[PATCH] pm3386: add hook for setting carrier
Add a pm3386 hook for disabling/enabling the SERDES carrier, so that we can disable it when the interface is administratively downed, and enable it when it is upped. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
