From 1a52d37fc50acd479274c29c2e92b05cf32c3a6d Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Thu, 4 Feb 2021 11:33:32 +0000 Subject: ipsec: one thread index per-SA Type: improvement AN SA is uni-drectional therefore it can be used only for encrypt or decrypt, not both. So it only needs one thread ID. free up some space on the 1st cacheline.
