Subject: [dpdk-dev] [PATCH v1 01/15] net/mlx5: fix send queue doorbell typo
Date: Thu,  1 Oct 2020 14:09:12 +0000
Message-ID: <1601561366-1821-2-git-send-email-michaelba@nvidia.com> (raw)
In-Reply-To: <1601561366-1821-1-git-send-email-michaelba@nvidia.com>

As part of SQ creation for Tx queue objects, a HW doorbell memory should
be allocated and mapped to the HW.

The SQ doorbell handler was wrongly saved on the CQ fields what caused
wrong doorbell release in the Tx queue object destroy flow.

Save the SQ doorbell handler in the SQ fields.

Fixes: 3a87b964edd3 ("net/mlx5: create Tx queues with DevX")
Cc: stable@dpdk.org
