New netfilter modules (xt_TRACE, xt_connlimit,
xt_u32, xt_gateway, xt_TARPIT, xt_time) and
tproxy4 have been added. A number of patches have
been outsourced to standalone packages.
ipt_layer7 has been ported to 2.6.20.2. Other
additions include RAIF, ipt_{ACCOUNT,ipp2p,time},
and Miklos' /proc/$$/fdinfo patch. This was
verified to create no unresolvable conflicts
against the vanilla 2.6.20.2 kernel.
