Subject: RE: [PATCH] net/mlx5: fix error CQE dumping for vectorized Rx burst
Date: Mon, 6 Feb 2023 15:05:13 +0000 [thread overview]
Message-ID: <DM4PR12MB5389B9CB3DF5AC8C88227B13DFDA9@DM4PR12MB5389.namprd12.prod.outlook.com> (raw)

From: Alexander Kozyrev
> There is a dump file with debug information created for an error CQE to help
> with troubleshooting later.
> It starts with the last CQE, which, presumably is the error CQE.
> But this is only true for the scalar Rx burst routing since we handle CQEs there
> one by one and detect the error immediately.
> For vectorized Rx bursts, we may already move to another CQE when we
> detect the error since we handle CQEs in batches there.
> Go back to the error CQE in this case to dump proper CQE.
