DPDK PCIe-VFIO framework configures base MSIX vector for interrupts
which is supported by other h/w. In case of bnxt, base MSIX vector
starts with the RX completion queue 0. To comply with the DPDK
framework We need to increase the map index by 1 so that RXTX
completion queues events can be delivered to appropriate event listeners
by kernel VFIO.

When updating the link because of an async link notification
there is no need to set wait_for_completion. At this point
the link related information should be available without need to poll.
Use rte_eth_linkstatus_set instead of memcpy to ensure atomicity
while updating the link status.
We force the physical link down as a part of device stop.
But we are not waiting there enough and handling the async notification
before exiting. It just sits in the default CQ till we do a device
start.
Fix it by calling the CQ handler in device stop.

rte_intr_callback_unregister() can fail if the handler happens to
be active at the time of the call. Add logic to retry a reasonable
number of times to help ensure that the callback is unregistered
on uninit.

This patch adds support to get Link notification asynchronously.
The HW sends async notifications on default completion ring. The
PMD processes these notifications and logs a message appropriately.
