Subject: [PATCH 10/13] net/ice: use common AVX Tx functions
Date: Thu,  3 Sep 2026 18:03:50 +0100	[thread overview]
Message-ID: <20260903170351.360967-1-bruce.richardson@intel.com> (raw)
In-Reply-To: <20260903170140.360477-1-bruce.richardson@intel.com>

Use the newly created common Tx functions in the vector path.
