Merge branch 'netxen'

Manish Chopra says:

====================
netxen: Bug fixes.

This series fixes some TX specific issues.
* Move spin_lock(tx_clean_lock) in down path to fix
  atomic sleep bug (Reported by Mike Galbraith).
* Fix hang in interface down while running traffic.

Please consider applying this to 'net'.
