[dpdk-dev] [PATCH 06/28] bnxt: add new HWRM commands to query VNIC info

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

This patch adds the following HWRM commands which will be used by
the subsequent patches.

- hwrm_func_vf_vnic_ids_query:
  This command is used to query vf vnic ids.

- hwrm_vnic_qcfg:
  Query the RX VNIC structure. This function can be used by a PF or a VF
  driver to query its own VNIC resource or VNIC resource of its child VF.
