From: Thomas Graf Date: Fri, 3 Sep 2010 03:04:20 +0000 (+0000) Subject: ipv6: add special mode forwarding=2 to send RS while configured as router X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c3bccac2fa76f1619dfe4fb7b9bee69de7f066d8;p=linux.git ipv6: add special mode forwarding=2 to send RS while configured as router Similar to accepting router advertisement, the IPv6 stack does not send router solicitations if forwarding is enabled. This patch enables this behavior to be overruled by setting forwarding to the special value 2. Signed-off-by: Thomas Graf Signed-off-by: David S.
