Subject: [PATCH 03/11] net/nfp: fix the DMA error caused by app exit abnormally
Date: Thu, 2 Nov 2023 10:23:13 +0800 [thread overview]
Message-ID: <20231102022321.2254224-4-chaoyong.he@corigine.com> (raw)
In-Reply-To: <20231102022321.2254224-1-chaoyong.he@corigine.com>
From: Shihong Wang <shihong.wang@corigine.com>
When DPDK application exit abnormally, there might have DMA error,
and which will cause the load of firmware failed.
Fix this by force the physical port down to clear the possible DMA error.
Fixes: 896c265ef954 ("net/nfp: use new CPP interface")
