During initialization sequence in bnxt_alloc_mem()
if bnxt_alloc_async_cp_ring() fails, driver invokes bnxt_free_mem()
which in turn call bnxt_free_vnic_mem() which causes the error logs
"bnxt_free_vnic_mem(): VNIC is not freed yet!". This is because
vnic memory is allocated but not initialized yet.
Fix this by moving bnxt_init_vnics() from bnxt_init_nic() to
bnxt_alloc_vnic_mem(). Also get rid of bnxt_init_nic() as the
initialization is done in respective functions now.

Transmit and receive queues are freed during reset cleanup and

in this state. The eth_dev dev_started field is updated depending

This commit enables the creation of a dedicated completion
ring for asynchronous event handling instead of handling these
events on a receive completion ring.
For the stingray platform and other platforms needing tighter
control of resource utilization, we retain the ability to
process async events on a receive completion ring.
For Thor-based adapters, we use a dedicated NQ (notification
queue) ring for async events (async events can't currently
be received on a completion ring due to a firmware limitation).
Rename "def_cp_ring" to "async_cp_ring" to better reflect its
purpose (async event notifications) and to avoid confusion with
VNIC default receive completion rings.
Allow rxq 0 to be stopped when not being used for async events.

free it as a part of queue_release dev_op.

Add a top level functions to initialize ring groups, and functions
to allocate and free all the rings via HWRM.
A ring group is identified by an index. It consists of Rx or Tx ring id,
completion ring id and a statistics context. Once a ring group is
initialized, use this group index while creating the rings in the ASIC
using the appropriate HWRM API added via earlier patches.
Functions added:
bnxt_free_cp_ring
Calls the HWRM function generic ring free with arguments specific
to a completion ring and sanitizes the host completion structure
bnxt_free_all_hwrm_rings
Frees all the HWRM allocated hardware rings
bnxt_free_all_hwrm_resources
Frees all the resources allocated via the HRM in the hardware
bnxt_alloc_hwrm_rings
Allocates all the HWRM rings needed in the current configuration
This should be the last functionality needed to add start/stop

Initial implementation of tx_pkt_burst for transmit.
bnxt_xmit_pkts() is the top level function that is called during Tx.
bnxt_handle_tx_cp() is used to check and process the Tx completions
generated for the Tx Buffer Descriptors sent by the hardware.
This patch also adds code to allocate rings in the hardware.
For each Tx queue allocated in the PMD driver, a corresponding ring
in hardware will be created. Every time a Tx request is initiated
via the bnxt_xmit_pkts() call, a Buffer Descriptor is created and
is sent to the hardware via the associated Tx ring.
On completing the Tx operation, the hardware will generates the status
in the form of a completion. This completion is processed by the
bnxt_handle_tx_cp() function.
Functions like bnxt_init_tx_ring_struct() and bnxt_init_one_tx_ring()
are used to initialize various members of the structure before
starting Tx operations.
