2.6.27-stable review patch.  If anyone has any objections, please let us know.

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

From: Stephen Hemminger <shemminger@vyatta.com>

Based on commit b63365a2d60268a3988285d6c3c6003d7066f93a upstream, but
drastically cut down for 2.6.27.y

The bridge device always causes a warning because when it is first created
it has the no checksum flag set along with all the segmentation/fragmentation
offload bits.  The code in register_netdevice incorrectly checks for only
hardware checksum bit and ignores no checksum bit.

Similar code is already in 2.6.28:
