From f60f6b8f70c756fc786d68f02ec17a1e84db645f Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 18 Jun 2005 22:44:37 -0700 Subject: [IPSEC] Use XFRM_MSG_* instead of XFRM_SAP_* This patch removes XFRM_SAP_* and converts them over to XFRM_MSG_*. The netlink interface is meant to map directly onto the underlying xfrm subsystem. Therefore rather than using a new independent representation for the events we can simply use the existing ones from xfrm_user.
