From 7d4e3919592593594296944ae7da1a207706e8c5 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 10 Jun 2020 09:14:35 -0700 Subject: esp, ah: consolidate the crypto algorithm selections Instead of duplicating the algorithm selections between INET_AH and INET6_AH and between INET_ESP and INET6_ESP, create new tristates XFRM_AH and XFRM_ESP that do the algorithm selections, and make these be selected by the corresponding INET* options.
