Subject: [PATCH 1/1] net/i40e: unset vector flag when scalar path is chosen
Date: Wed, 17 Dec 2025 14:54:36 +0000 [thread overview]
Message-ID: <20251217145436.3217068-2-ciara.loftus@intel.com> (raw)
In-Reply-To: <20251217145436.3217068-1-ciara.loftus@intel.com>
The tx_vec_allowed flag should be set to false if a scalar Tx path is
chosen.
Fixes: 1ff08bb7ad90 ("net/i40e: use common Tx path selection infrastructure")
