ebtables match inverted in 2.6.28?

["Matt Cross" <matt.cross@gmail.com>]

I think the work to move ebtables to use xtables broke ebtables.
Specifically, in commit 8cc784eec6676b58e7f60419c88179aaa97bf71c the
return value of the match functions was inverted so that they return 1
(true) on matches instead of EBT_MATCH (0), and vice versa (look in
ebt_ip.c).  The logic in ebtables.c (ebt_do_table() and
EBT_MATCH_ITERATE()) expect match functions to return 0 for matches.

The patch at the end of this message fixes the problem, but seems a
little hacky to me.  Who's the right person to address this?
