From: Yoray Zack <redacted>
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.
