Subject: [PATCH net-next 1/2] mcast: define and use MRT[6]_MAX in ip[6]_mroute_opt()
Date: Fri, 18 Jan 2013 17:59:37 +0100	[thread overview]
Message-ID: <1358528378-2110-2-git-send-email-nicolas.dichtel@6wind.com> (raw)
In-Reply-To: <1358528378-2110-1-git-send-email-nicolas.dichtel@6wind.com>

This will ease further addition of new MRT[6]_* values and avoid to update
in6.h each time.
Note that we reduce the maximum value from 210 to 209, but 210 does not match
any known value in ip[6]_mroute_setsockopt().
