From 136ebf08b46f839e2dc9db34322b654e5d9b9936 Mon Sep 17 00:00:00 2001 From: Masahide NAKAMURA Date: Tue, 26 Jun 2007 23:51:41 -0700 Subject: [PATCH] [IPV6] MIP6: Kill unnecessary ifdefs. Kill unnecessary CONFIG_IPV6_MIP6. o It is redundant for RAW socket to keep MH out with the config then it can handle any protocol. o Clean-up at AH.
