Subject: [PATCH V1 net 08/13] net: ena: add support for reporting of packet drops
Date: Wed, 22 Apr 2020 08:09:18 +0000	[thread overview]
Message-ID: <20200422080923.6697-9-sameehj@amazon.com> (raw)
In-Reply-To: <20200422080923.6697-1-sameehj@amazon.com>

From: Sameeh Jubran <sameehj@amazon.com>

1. Add support for getting tx drops from the device and saving them
in the driver.
2. Report tx and rx drops via ethtool.
3. Report tx via netdev stats.
