Subject: [dpdk-stable] [PATCH 06/11] net/sfc: fix accessing xstats by an unsorted list of IDs
Date: Fri,  4 Jun 2021 17:42:20 +0300	[thread overview]
Message-ID: <20210604144225.287678-7-andrew.rybchenko@oktetlabs.ru> (raw)
In-Reply-To: <20210604144225.287678-1-andrew.rybchenko@oktetlabs.ru>

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

Device may support only some MAC stats. Add mapping from ids to subset
of supported MAC stats for each port.

Fixes: 73280c1e4ff ("net/sfc: support xstats retrieval by ID")
