Subject: [dpdk-dev] [PATCH 20.05 04/15] common/mlx5: replace alignas keyword
Date: Mon, 10 Feb 2020 17:20:21 +0100	[thread overview]
Message-ID: <20200210162032.1177478-5-thomas@monjalon.net> (raw)
In-Reply-To: <20200210162032.1177478-1-thomas@monjalon.net>

The keyword alignas can be replaced with __rte_aligned macro
for consistency and allow compilers compatibility control.

The macro __rte_cache_aligned is a shortcut including __rte_aligned
and RTE_CACHE_LINE_SIZE constant.
