Packets destined to the to-be-stopped queue should not be dropped
(neither in HW nor in the driver), so re-program the RSS Table without
this queue on stop and add it back to the table on start unless it
is a Representor VF.
Since 0th entry is used for default ring, use fw_grp_id + 1 to change
the RSS table population logic by programming valid IDs instead of the
default zeroth entry in case of an invalid fw_grp_id.
Destroy and recreate the trio of Rx rings(compl, Rx, AG) every time in
start so that HW is in sync with software.

If the resource requirement of a VF is more than what is allotted
to it by the FW, a VF can request to reallocate some of the resources.
This is possible only when the NIC is running the Resource Manager aware
CHiMP FW.
If necessary, calculate Tx and Rx ring count using the new RM API.
Otherwise use the Tx and Rx ring count as-is. Update the cp ring count
based on the Tx and Rx ring count.

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.
