Subject: [10/18] netxen: fix set mac addr

2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------

From: Amit Kumar Salecha <amit.salecha@...gic.com>

commit d49c9640975355c79f346869831bf9780d185de0 upstream.

o If tx and rx resources are not available, during set mac request.
  Then this request wont be passed to firmware and it will be added to
  driver mac list and will never make it to firmware.
  So if resources are not available, don't add it to driver mac list.
