Subject: [net V2 12/15] net/mlx5e: kTLS, Add missing dma_unmap in RX resync
Date: Mon, 21 Sep 2020 17:30:58 -0700 [thread overview]
Message-ID: <20200922003101.529117-13-saeed@kernel.org> (raw)
In-Reply-To: <20200922003101.529117-1-saeed@kernel.org>
From: Saeed Mahameed <saeedm@nvidia.com>
Progress params dma address is never unmapped, unmap it when completion
handling is over.
Fixes: 0419d8c9d8f8 ("net/mlx5e: kTLS, Add kTLS RX resync support")
