From ce7a3bdf18a8dbcba1409f5d335c56fde432ca89 Mon Sep 17 00:00:00 2001 From: Florent Fourcot Date: Tue, 10 Dec 2013 15:15:46 +0100 Subject: [PATCH] ipv6: do not erase dst address with flow label destination This patch is following b579035ff766c9412e2b92abf5cab794bff102b6 "ipv6: remove old conditions on flow label sharing" Since there is no reason to restrict a label to a destination, we should not erase the destination value of a socket with the value contained in the flow label storage. This patch allows to really have the same flow label to more than one destination. Signed-off-by: Florent Fourcot Reviewed-by: Hannes Frederic Sowa Signed-off-by: David S.
