[dpdk-dev] [PATCH v3 5/8] ixgbe: implement ops of 'dev_infos_get' for PF and VF respectively

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

As more and more information are different between PF and VF, ops of
'dev_infos_get' has been implemented respectively. In addition,
returning redirection table size has been supported in it.

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

v3 changes:
* Returning default RX/TX configurations has been added in ops of
  'dev_infos_get' for VF, as it was added recently in that for PF.
