Incremental checksum updates for 2.2.19-1.0.8

[Julian Anastasov <ja@xxxxxx>]

        Hello,

        I just uploaded fastcsum-1.0.8-2.2.19-1.diff in
http://www.linuxvirtualserver.org/~julian/fastcsum-1.0.8-2.2.19-1.diff

        This patch includes the same optimizations we can see in the
development IPVS 0.9.4 for 2.4, i.e. incremental checksum updates for
all LVS-NAT connections and in the 2.2 case even for the masqueraded
(non-LVS) ones.

        This is a 1.0.9 candidate, so your test results are welcome. The
reason to announce it before 1.0.9 is to allow some LVS users to test it
and to report their results. The interesting part is whether there is a
speed improvement for the NAT processing. Of course, such tests can
be performed with CONFIG_IP_ROUTER defined (if used from your NIC at all).
If everything is ok, we will see a new 1.0.9 release (the last was from
May).

Regards
