Subject: [PATCH 6/7] net/null: replace rte atomics with GCC builtin atomics
Date: Fri, 17 Mar 2023 13:19:47 -0700	[thread overview]
Message-ID: <1679084388-19267-7-git-send-email-roretzla@linux.microsoft.com> (raw)
In-Reply-To: <1679084388-19267-1-git-send-email-roretzla@linux.microsoft.com>

Replace the use of rte_atomic.h types and functions, instead use GCC
supplied C++11 memory model builtins.
