The interface name matching has shown up in profiles forever

Eric, I'm trying to keep all the *tables files synchronized,
could you send me a patch updating the other ones as well
please?
While doing this, I found arp_tables is still using loop using
byte operations.
Also, I could not find how iniface_mask[], outiface_mask[], iniface[]
and outiface[] were forced to long word alignment ...
(in struct ipt_ip, struct ip6t_ip6, struct arpt_arp)
In case of IPv4 and IPv6 they are already suitable aligned, it
simply performing the comparison in unsigned long quantities.
struct arpt_arp unfortunately doesn't properly align the interface
names, so we need to continue to do byte-wise comparisons.
