Subject: [PATCH v3 01/13] net/ionic: add stat for completion queue entries processed
Date: Tue, 6 Feb 2024 19:13:05 -0800	[thread overview]
Message-ID: <20240207031317.32293-2-andrew.boyer@amd.com> (raw)
In-Reply-To: <20240207031317.32293-1-andrew.boyer@amd.com>

When completion coalescing is turned on in the FW, there will be
fewer CQE than Tx packets. Expose the stat through debug logging.
