sky2: force receive checksum when using RSS on some hardware (v2)

Found when reviewing the vendor driver. Apparently some chip versions
require receive checksumming to be enabled in order for RSS to work.

Also, if fix_features has to change some settings; put in message
in log in similar manner to netdev_fix_features.

going to powersave state when there are still untransmitted TX frames

to a fanout.  All AF_PACKET sockets trying to join the same fanout
must all have the same bind settings.

Fanouts are identified (within a network namespace) by a 16-bit ID.
The first socket to try to add itself to a fanout with a particular
ID, creates that fanout.  When the last socket leaves the fanout
(which happens only when the socket is closed), that fanout is
