eth2: New link status: Connected (0001)

If I set this network card down and try to bring it back up, all net
device access stalls in D state. No dmesg, no panics, nadda.

I've seen a similar problem with tg3 in virgin -test5 and with hostap in
-test4-mm5. I believe I read it was due to something failing to
release the rtnl semaphore?
