Subject: [PATCH] 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The document about rp_filter is out of date.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.
