Subject: [dpdk-dev] [PATCH] app/flow-perf: use macro for cache alignment
Date: Mon, 29 Jun 2020 23:04:42 +0200
Message-ID: <20200629210443.371664-1-thomas@monjalon.net> (raw)

The macro __rte_cache_aligned is better suited for aligning
a structure on a cache line (of any size).

Fixes: 15c431864000 ("app/flow-perf: add packet forwarding support")
