Subject: RE: [PATCH] net/mlx5: check compressed CQE opcode for an error
Date: Mon, 6 Feb 2023 15:05:50 +0000 [thread overview]
Message-ID: <DM4PR12MB53894EB84B8AC2824DE72ED5DFDA9@DM4PR12MB5389.namprd12.prod.outlook.com> (raw)

From: Alexander Kozyrev
> The CQE opcode is never checked for a compressed CQE in the vectorized Rx
> burst routines. It is assumed that compressed CQEs are always valid and
> skipped error checking.
>
> This is obviously not the case and error CQEs may be compressed together as
> well. Need to check for the MLX5_CQE_RESP_ERR opcode and mark all the
> packets as bad ones in the compression session if it is there.

> Note that this issue is not applicable to the scalar Rx burst.
