Introduce xt_length match revision 1. It adds support for layer-4,

This can be used for packet scheduling; specific example are online
games where all data is transferred over the same port, but the
regular gameplay has a characteristically lower packet size than bulk
downloads of game maps. (Tested with Unreal Tournament 99.)
I'll let this sit on the list for a few more days in case
someone else has comments. I'm personally not a huge fan
of bloating this length module like this. Perhaps something
more minimalistic would also do the trick?
Have something special in mind?
In my opinion all the kernel should needs to be able to do
is to deal with variable length headers, everything else can
be calculated by userspace(/the user).
So for example if you can match on the IP payload length,
you *know* the UDP data length is that value - 8.
Whats that SCTP thing about?
