Subject: [PATCH] net/mlx5: revert fallback to Verbs Tx allocation
Date: Mon, 20 Jul 2026 13:49:29 +0200	[thread overview]
Message-ID: <20260720114929.2998238-1-thomas@monjalon.net> (raw)

On Windows, DevX CQ creation was failing because
of a different allocation fallback behaviour.

Fixes: 4abc12b9331c ("net/mlx5: fall back to Verbs Tx allocation without DevX")
Cc: stable@dpdk.org
