LARTC - Mar 2003 - [PATCH 2.4.21-pre4] Propagate netfilter MARK value when tunneling

This patch enables the user to propagate netfilter MARK values from
tunneled packets to the tunnel packets. The primary use for this is QoS: it
enables you to MARK a packet before it enters a tunnel and then later pick
up the packet when it''s about to leave the physical interface.

jamal <hadi@cyberus.ca> suggested to also propagate other skb specifics
like the tcindex and priority. I haven''t included these in the current
patch for the very simple reason that I don''t understand what they mean
;-)

The patch is currently limited to GRE, IPIP and SIT.

Patch is attached to this mail, but also can be downloaded from
