Hans Petter Selasky e53c3826c0 mlx5en: Implement support for internal queues, IQ.
Internal send queues are regular sendqueues which are reserved for WQE commands
towards the hardware and firmware. These queues typically carry resync
information for ongoing TLS RX connections and when changing schedule queues
for rate limited connections.

The internal queue, IQ, code is more or less a stripped down copy
of the existing SQ managing code with exception of:

1) An optional single segment memory buffer which can be read or
   written as a whole by the hardware, may be provided.
2) An optional completion callback for all transmit operations, may
   be provided.
3) Does not support mbufs.
