Subject: [PATCH iwl-next 3/3] i40e: Use helpers to check running FW and AQ API versions
Date:   Mon, 23 Oct 2023 18:29:28 +0200
Message-ID: <20231023162928.245583-4-ivecera@redhat.com>
In-Reply-To: <20231023162928.245583-1-ivecera@redhat.com>
References: <20231023162928.245583-1-ivecera@redhat.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use new helpers to check versions of running FW and provided
AQ API to make the code more readable.
