ip: update the description of rp_filter in ip-sysctl.txt
The commit 27fed4175acf81ddd91d9a4ee2fd298981f60295 (ip: fix logic of reverse path filter sysctl) has changed the logic of rp_filter. The document about rp_filter is out of date. Now, setting conf/all/rp_filte with 0 can also enable source validation. Update the document according to the commit. Signed-off-by: Shan Wei <shanwei@cn.fujitsu.com> Signed-off-by: David S.
