Subject: [dpdk-dev] [PATCH 09/11] net/sfc: prepare to add more xstats
Date: Fri,  4 Jun 2021 17:42:23 +0300
Message-ID: <20210604144225.287678-10-andrew.rybchenko@oktetlabs.ru> (raw)
In-Reply-To: <20210604144225.287678-1-andrew.rybchenko@oktetlabs.ru>

From: Ivan Ilchenko <ivan.ilchenko@oktetlabs.ru>

Move getting MAC stats code that involves locking to separate functions
to simplify addition of new xstats.
