Subject: [PATCH]ipv6:remove useless check

From: Yang Hongyang <[email-masked]>
Date: Tue, 14 Apr 2009 09:51:00 +0800

After switch (rthdr->type) {...},the check below is completely useless.Because:
if the type is 2,then hdrlen must be 2 and segments_left must be 1,clearly the
check is redundant;if the type is not 2,then goto sticky_done,the check is useless
too.
