Subject: RDMA/mlx5: Remove ECE limitation from the RAW_PACKET QPs
Patch-mainline: v5.8-rc3
Git-commit: 2c0f5292d5358c2c5576146071d641110c3c1612
References: jsc#SLE-15175
Like any other QP type, rely on FW for the RAW_PACKET QPs to decide if ECE
is supported or not. This fixes an inability to create RAW_PACKET QPs with
latest rdma-core with the ECE support.
Fixes: e383085c2425 ("RDMA/mlx5: Set ECE options during QP create")
