From 570617e79c3ab31ce426efe9024af84efca862eb Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Tue, 12 Feb 2013 05:15:33 +0000 Subject: net: sctp: remove unused multiple cookie keys Vlad says: The whole multiple cookie keys code is completely unused and has been all this time. Noone uses anything other then the secret_key[0] since there is no changeover support anywhere. Thus, for now clean up its left-over fragments.
