From a7e830ed468f35590871988e68153222325870b8 Mon Sep 17 00:00:00 2001 From: Mohsin Kazmi Date: Fri, 23 Apr 2021 15:16:50 +0200 Subject: vlib: move offload flags to 1st cacheline in vlib_buffer_t Type: improvement Some tests i.e. ipsec see performance regression when offload flags are moved to 2nd cacheline. This patch moves them back to 1st cacheline.
