Hi Patrick

Please find following patch to prepare next one (loop unrolling)

I am not sure xt_physdev_info is aligned, either on an int or a long,
so please check my assertion before applying :)

Yes, the private structures can assume alignment suitable for
pointers and unsigned longs.

[PATCH] netfilter: xt_physdev fixes

1) physdev_mt() incorrectly assumes nulldevname[] is aligned on an int

2) It also uses word comparisons, while it could use long word ones.

Applied, thanks.
