Subject: [PATCH net-next v2 5/8] bnxt: add pause frame stats
Date: Fri, 11 Sep 2020 16:28:50 -0700	[thread overview]
Message-ID: <20200911232853.1072362-6-kuba@kernel.org> (raw)
In-Reply-To: <20200911232853.1072362-1-kuba@kernel.org>

These stats are already reported in ethtool -S.
Michael confirms they are equivalent to standard stats.

v2: - fix sparse warning about endian by using the macro
    - use u64 for pointer type
