History
Laszlo Attila Toth 4a19ec5800 [NET]: Introducing socket mark socket option. 
A userspace program may wish to set the mark for each packets its send
without using the netfilter MARK target. Changing the mark can be used
for mark based routing without netfilter or for packet filtering.

It requires CAP_NET_ADMIN capability.
