[PATCH net 3/3] net/mlx5e: Expose CQE moderation mode on representors

[Tariq Toukan <tariqt@nvidia.com>]

From: Yael Chemla <ychemla@nvidia.com>

commit bc541621f8ba ("net/mlx5e: Support ethtool cq mode") added
ETHTOOL_COALESCE_USE_CQE to the NIC ethtool ops but omitted it from
mlx5e_rep_ethtool_ops.supported_coalesce_params. The ethtool netlink
layer rejects any attempt to set cqe-mode-rx/tx on a representor
with EINVAL.

Add ETHTOOL_COALESCE_USE_CQE to mlx5e_rep_ethtool_ops.
mlx5e_ethtool_set_coalesce() already handles it correctly.

Fixes: bc541621f8ba ("net/mlx5e: Support ethtool cq mode")
