   Memory allocation is also being done in the init path.

   should be controllable.

   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.

one at a time and tx coalescing has to wait for ETH_COALESCE_PKT

- Update rx path to use status page instead and only receive packets

  the ingress interrupt packet count threshold (32 packets) fires.

- If number of packets coalesced is <= number of packets sent
