Doc: Refer to ip-sysctl.txt for strict vs. loose rp_filter mode
The IP_ADVANCED_ROUTER Kconfig describes the rp_filter proc option. Recent changes added a loose mode. Instead of documenting this change too places, refer to the document describing it: Documentation/networking/ip-sysctl.txt I'm considering moving the rp_filter description away from the Kconfig file into ip-sysctl.txt.
