From 46306b49349ba9c4e5bdb9cb3c4e8b50192106bf Mon Sep 17 00:00:00 2001 From: Li RongQing Date: Mon, 23 Dec 2013 09:32:38 +0800 Subject: [PATCH] ipv6: unneccessary to get address prefix in addrconf_get_prefix_route Since addrconf_get_prefix_route inputs the address prefix to fib6_locate, which does not uses the data which is out of the prefix_len length, so do not need to use ipv6_addr_prefix to get address prefix.
