Subject: [PATCH 2/2] net/gve: add extended statistics
Date: Thu, 16 Feb 2023 21:58:14 +0300	[thread overview]
Message-ID: <20230216185814.27830-2-levendsayar@gmail.com> (raw)
In-Reply-To: <20230216185814.27830-1-levendsayar@gmail.com>

Google Virtual NIC PMD is enriched with extended statistics info.
eth_dev_ops callback names are also synched with eth_dev_ops field names
