Subject: [PATCH v19 16/20] net/mlx5e: NVMEoTCP, queue init/teardown

From: Ben Ben-Ishay <benishay@...dia.com>

Adds the ddp ops of sk_add, sk_del and offload limits.

When nvme-tcp establishes new queue/connection, the sk_add op is called.
We allocate a hardware context to offload operations for this queue:
- use a steering rule based on the connection 5-tuple to mark packets
  of this queue/connection with a flow-tag in their completion (cqe)
- use a dedicated TIR to identify the queue and maintain the HW context
- use a dedicated ICOSQ to maintain the HW context by UMR postings
- use a dedicated tag buffer for buffer registration
- maintain static and progress HW contexts by posting the proper WQEs.

When nvme-tcp teardowns a queue/connection, the sk_del op is called.
We teardown the queue and free the corresponding contexts.

The offload limits we advertise deal with the max SG supported.

[Re-enabled calling open/close icosq out of en_main.c]
