Inquire firmware on supported offloads, as well as convey offloads
enabled dynamically to firmware. New control net API functionality is
required for the above. Implement control net API framework for
offloads.
Additionally, fetch/insert offload metadata from hardware RX/TX
buffer respectively during receive/transmit.
Currently supported offloads include checksum and TSO.

Set backpressure watermark for hardware RX queues. Backpressure
gets triggered when the available buffers of a hardware RX queue
falls below the set watermark. This backpressure will propagate
to packet processing pipeline in the OCTEON card, so that the host
receives fewer packets and prevents packet dropping at host.

Max receive packet length can vary across SoCs, so
this needs to be queried from respective firmware and
filled by driver. A control net get mtu api should be
implemented to do the same.

Replace atomic variable "instr_pending" which represents number of
posted tx instructions pending completion, with host_write_idx and
flush_index variables in the xmit and completion processing respectively.

Monitor periodic heartbeat messages from device firmware.
Presence of heartbeat indicates the device is active and running.
If the heartbeat is missed for configured interval indicates
firmware has crashed and device is unusable; in this case, PF driver
stops and uninitialize the device.
