[dpdk-dev] [PATCH v2 07/13] ixgbe: add new function for VF ops of 'dev_infos_get'

[Helin Zhang <helin.zhang@intel.com>]

New function of 'ixgbevf_dev_info_get' has been added for
VF ops of 'dev_infos_get', as more and more information
are different between PF and VF.

v2 changes:
* Added new function for ops of 'dev_infos_get' specifically
  for ixgbe VF.
