From 04ff12609445c7b462d7fc7f2d30dad442c922f3 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 13 Aug 2006 08:50:00 +1000 Subject: [IPSEC]: Add compatibility algorithm name support This patch adds a compatibility name field for each IPsec algorithm. This is needed when parameterised algorithms are used. For example, "md5" will become "hmac(md5)", and "aes" will become "cbc(aes)".
