Subject: [PATCH] skge: restore device multicast membership after link down/up

Yukon hardware will lose multicast membership data and promiscuous mode 
information if a link is disconnected and reconnected without taking the
interface down.  A call to yukon_reset in yukon_link_down will clear the
hardware's multicast list, so it needs to be added back on link_up.

It does not appear that Genesis hardware needs a similar patch is needed
since it does not seem to clear multicast membership when taking the
link down.
