Allows you to apply a Netfilter mark value to outgoing packets
	on the server side, based on an ACL.

	tcp_outgoing_mark mark-value [!]aclname ...

	Example where normal_service_net uses the mark value 0x00
	and good_service_net uses 0x20

	acl normal_service_net src 10.0.0.0/24
	acl good_service_net src 10.0.1.0/24
	tcp_outgoing_mark 0x00 normal_service_net
	tcp_outgoing_mark 0x20 good_service_net

	Only fast ACLs are supported.
