From f04e7e8d7f175c05bbde3ae748bf2541da53721d Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 13 Nov 2007 21:36:51 -0800 Subject: [IPSEC]: Replace x->type->{local,remote}_addr with flags The functions local_addr and remote_addr are more than what they're needed for. The same thing can be done easily with flags on the type object. This patch does that and simplifies the wrapper functions in xfrm6_policy accordingly.
