Subject: [PATCH v5 net-next 27/36] mlx5e: make preparation in TLS code for NVMEoTCP CRC Tx offload
Date: Thu, 22 Jul 2021 14:03:16 +0300 [thread overview]
Message-ID: <20210722110325.371-28-borisp@nvidia.com> (raw)
In-Reply-To: <20210722110325.371-1-borisp@nvidia.com>
From: Yoray Zack <yorayz@nvidia.com>
NVMEoTCP CRC Tx offload is similar to TLS Tx offload,
and uses DUMP wqe as well.
To avoid duplicate functions the following changes were added:
1. Add DUMP_WQE.type field (=TLS or NVMEoTCP).
2. change in mlx5e_ktls_tx_handle_resync_dump_comp
to handle also NVMEoTCP Tx DUMP WQE.
Signed-off-by: Yoray Zack <yorayz@nvidia.com>
