Subject: [PATCH net-next v2 8/9] bnxt: implement ethtool standard stats
Date: Fri, 16 Apr 2021 12:27:44 -0700	[thread overview]
Message-ID: <20210416192745.2851044-9-kuba@kernel.org> (raw)
In-Reply-To: <20210416192745.2851044-1-kuba@kernel.org>

Most of the names seem to strongly correlate with names from
the standard and RFC. Whether ..+good_frames are indeed Frames..OK
I'm the least sure of.
