[PATCH net 06/14] docs: tproxy: ignore non-transparent sockets in iptables

[Pablo Neira Ayuso <pablo@netfilter.org>]

From: 谢致邦 (XIE Zhibang) <Yeking@Red54.com>

The iptables example was added in commit d2f26037a38a (netfilter: Add
documentation for tproxy, 2008-10-08), but xt_socket 'transparent'
option was added in commit a31e1ffd2231 (netfilter: xt_socket: added new
revision of the 'socket' match supporting flags, 2009-06-09).

Now add the 'transparent' option to the iptables example to ignore
non-transparent sockets, which is also consistent with the nft example.

 socket on your box, set the packet mark to a certain value::
