Subject: [net-next V2 04/15] net/mlx5e: Allow SQ outside of channel context
From: Eran Ben Elisha <eranbe@...dia.com>
In order to be able to create an SQ outside of a channel context, remove
sq->channel direct pointer. This requires adding a direct pointer to:
netdevice, priv and mlx5_core in order to support SQs that are part of
mlx5e_channel. Use channel_stats from the corresponding CQ.
