63d499f0c4 net/bnxt: fix set link config
bnxt_hwrm_port_phy_cfg() was not setting enables appropriately.
This was causing undesired issues with link config.
This patch takes care of that.

1cd45aeb32 net/bnxt: support Stratus VF device
This patch adds support for Stratus VF devices.
Other than adding the VF device ID, we also are adding
support for short message format.

The new short firmware message of size 16 bytes points to a location
in host memory that contains the firmware message that the driver
wants the adapter to process. This indirection requires the
firmware to DMA the message into its own memory for processing.

When the firmware receives a Short Command Format, it will DMA the
firmware message from host memory into its internal memory and then
processes the message as it would have if it received the message
directly in the firmware communication channel.

With BCM57454, the number of VFs increase to 1K and so the requirement
for firmware communication channel memory on adapter becomes expensive.
The short firmware message saves the amount of memory required to support
1K VFs on adapter.

4535cad395 net/bnxt: handle VF/PF initialization appropriately
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.

b7778e8a1c net/bnxt: refactor to properly allocate resources for PF/VF
1) Move the function reset to bnxt_dev_init.
   On the same lines, setup, enable and request interrupt to init path.
   Memory allocation is also being done in the init path.

2) After a function reset, configure the VFs.  Distribute resources
   evenly between all functions (PF and VF) for now. In the future, this
   should be controllable.

3) The bnxt_vf_info and bnxt_pf_info had lot of duplication. Move the
   common items to struct bnxt. And only unique items specific to PF
   remain in the struct bnxt_pf_info.

4) Program the firmware to allow certain commands sent by a VF.
   Disallowing these will prevent clean VF driver cleanup.

5) Since PF/VF need to allocate resources from a pool in the hardware,
   use func_qcaps and func_qcfg to appropriately query the capabilities
   and available resources.

6) If a PF is being initialized and no VFs are allocated, explicitly
   call func_cfg to allocate the resources.

7) Once resources are requested from the firmware, update local copy
   of resource count in struct bnxt only after sending the func_qcfg to
   make sure the allocation request in the firmware went through.

The changes in this patch will be used by the subsequent patches
to allow proper initialization of PF/VF instance.

2523b1584c net/bnxt: add HWRM function reset command
Add bnxt_hwrm_func_reset() function and supporting structs and macros.

New HWRM calls:
bnxt_hwrm_func_reset:
	This command puts the function into the reset state.
	In the reset state, global and port related features of the
	chip are not available.

This command resets a hardware function (PCIe function) and
frees any resources used by the function. This command initiated by
the driver prepare the function for re-use. This command may also be
initiated by a driver prior to doing it's own configuration.

57d5e5bc86 net/bnxt: add statistics
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.

New HWRM calls:
bnxt_hwrm_stat_clear:
	This command clears statistics of a context
