In the current model, VFs are not trusted.
So it is not allowed to send many HWRM commands.
Newer firmware has added support to allow VF to be trusted.
Now the VF queries if it is a trusted entity and based on that
it can send HWRM commands to the firmware.

In order to save completion resource, use the first completion ring from
PF or VF as the default completion ring for async event & HWRM forward
response handling. Add bnxt_hwrm_set_async_event_cr() to set
async_event_cr for either PF or VF.

This patch adds support to modify MTU using the set_mtu dev_op.
To support frames > 2k, the PMD creates an aggregator ring.
When a frame greater than 2k is received, it is fragmented
and the resulting fragments are DMA'ed to the aggregator ring.
Now the driver can support jumbo frames upto 9500 bytes.

1) For a VF, query the firmware to determine if a MAC address is
already configured. If not configure a random default MAC address.
2) Do not initialize the default completion ring in
bnxt_alloc_hwrm_rings().
3) While registering for async events with the firmware,
use func_vf_cfg for a VF and use func_cfg for a PF.
4) Query the VNIC plcmode config using the bnxt_hwrm_vnic_plcmodes_qcfg
before a VNIC is updated. Reconfigure the VNIC with the plcmode
configuration queried earlier. Not doing this could overwrite
the plcmodes in some cases.
5) Reorg the bnxt_handle_fwd_req to properly handle the forwarded
requests. The previous code did not handle it completely.

Perform allocation and free()ing of ring and information structures
for the TX, RX, and completion rings. The previous patches had
so far provided top level stubs and generic ring support, while this
patch does the real allocation and freeing of the memory specific to
each different type of generic ring.
For example bnxt_init_tx_ring_struct() or bnxt_init_rx_ring_struct() is
now allocating memory based on the socked_id being provided.
bnxt_tx_queue_setup_op() or bnxt_rx_queue_setup_op() have gone through
some reformatting to perform a graceful cleanup in case memory
allocation fails.

Add the bnxt_stats_get_op() and bnxt_stats_reset_op() dev_ops to
get and reset statistics. It also brings in the associated HWRM calls
to handle the requests appropriately.
We also have the bnxt_free_stats() function which will be used in the
follow on patches to free the memory allocated by the driver for
statistics.

Structures, macros, and functions for working with completion rings
in the driver.
Completion Ring is used by the Ethernet controller to provide the
status of transmitted & received packets, report errors, report
status changes to the host software, and inter-function forwarding
requests. In addition to the generic ring features, a completion ring
can have a statistics context that has statistics periodically DMAed
to host memory, along with a consumer index.
bnxt_handle_async_event() handles completions not related to a specific
transmit or receive ring such as link status changes which arrive on
the default completion ring.
Other physical or virtual functions on the same device may send an HWRM
command forward request. In this case, we will pass it through
unvalidated. In the future, we will be able to have the PF monitor and
control VF access to the HWRM interface if needed.
New HWRM Calls:
bnxt_hwrm_exec_fwd_resp:
Execute an encapsulated command and forward the response.
