Hi!

The udp-packet constructed in netpoll_send_udp should be aligned
to avoid alignment-traps on some platforms. The patch applies to
vanilla 2.6.11.2.

Ciao,
Sven

Patch applied, thanks Sven.

Please post networking patches in the future to netdev@oss.sgi.com,
as that is where the networking developers are.

Thanks.
