Subject: net/ipv6: Enforce limits for accept_unsolicited_na sysctl
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d09d3ec03f025fdc22e193277b30a7db20816d2b;p=linux.git

net/ipv6: Enforce limits for accept_unsolicited_na sysctl

Fix mistake in the original patch where limits were specified but the
handler didn't take care of the limits.
