---------------------------
What (Why):
- - include/linux/netfilter_ipv4/ipt_TOS.h ipt_tos.h header files
- (superseded by xt_TOS/xt_tos target & match)
-
- - "forwarding" header files like ipt_mac.h in
- include/linux/netfilter_ipv4/ and include/linux/netfilter_ipv6/
-
- - xt_CONNMARK match revision 0
- (superseded by xt_CONNMARK match revision 1)
-
- - xt_MARK target revisions 0 and 1
- (superseded by xt_MARK match revision 2)
-
- - xt_connmark match revision 0
- (superseded by xt_connmark match revision 1)
-
- - xt_conntrack match revision 0
- (superseded by xt_conntrack match revision 1)
-
- - xt_iprange match revision 0,
- include/linux/netfilter_ipv4/ipt_iprange.h
- (superseded by xt_iprange match revision 1)
-
- - xt_mark match revision 0
- (superseded by xt_mark match revision 1)
-
- xt_recent: the old ipt_recent proc dir
(superseded by /proc/net/xt_recent)
