ANDROID: net: ip-sysctl: Document tcp_fwmark_accept 



This documentation patch is the part of original tcp_fwmark_accept
implementation, Change-Id: I26bc1eceefd2c588d73b921865ab70e4645ade57
("net: support marking accepting TCP sockets").

The implementation since then got upstreamed, 84f39b08
("net: support marking accepting TCP sockets"), without this
documentation part.

tcp_fwmark_accept - BOOLEAN

	If set, incoming connections to listening sockets that do not have a

	socket mark will set the mark of the accepting socket to the fwmark of

	the incoming SYN packet. This will cause all packets on that connection

	(starting from the first SYNACK) to be sent with that fwmark. The

	listening socket's mark is unchanged. Listening sockets that already

	have a fwmark set via setsockopt(SOL_SOCKET, SO_MARK, ...) are

	unaffected.
