Start adding support to use the HWRM API.
Hardware Resource Manager or HWRM in short, is a set of API provided
by the firmware running in the ASIC to manage the various resources.
Initial commit just performs necessary HWRM queries for init, then
fails as before.
Now that struct bnxt is non-zero size, we can set dev_private_size
correctly.
The used HWRM calls so far:
bnxt_hwrm_func_qcaps:
This command returns capabilities of a function.
bnxt_hwrm_ver_get:
This function is called by a driver to determine the HWRM
interface version supported by the HWRM firmware, the
version of HWRM firmware implementation, the name of HWRM
firmware, the versions of other embedded firmwares, and
the names of other embedded firmwares, etc. Gets the
firmware version and interface specifications. Returns
an error if the firmware on the device is not supported
by the driver and ensures the response space is large
enough for the largest possible response.
bnxt_hwrm_queue_qportcfg:
This function is called by a driver to query queue
configuration of a port.
