Subject: [PATCH net-next 5/8] bnxt: add pause frame stats
Date: Fri, 11 Sep 2020 12:52:55 -0700	[thread overview]
Message-ID: <20200911195258.1048468-6-kuba@kernel.org> (raw)
In-Reply-To: <20200911195258.1048468-1-kuba@kernel.org>

These stats are already reported in ethtool -S.
Hopefully they are equivalent to standard stats?
