net: dsa: bcm_sf2: Fix Wake-on-LAN with mac_link_down()
[ Upstream commit b7be130c5d52e5224ac7d89568737b37b4c4b785 ]
After commit 2d1f90f9ba83 ("net: dsa/bcm_sf2: fix incorrect usage of
state->link") the interface suspend path would call our mac_link_down()
call back which would forcibly set the link down, thus preventing
Wake-on-LAN packets from reaching our management port.
Fix this by looking at whether the port is enabled for Wake-on-LAN and
not clearing the link status in that case to let packets go through.
