net/mlx5e: Remove ethernet segment from dump WQE
Dump WQE shall not include Ethernet segment. Define mlx5e_dump_wqe to be used for "Dump WQEs" instead of sharing it with the general mlx5e_tx_wqe layout. Fixes: d2ead1f360e8 ("net/mlx5e: Add kTLS TX HW offload support") Signed-off-by: Eran Ben Elisha <eranbe@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
