[dpdk-dev] [PATCH v3 6/8] i40e: rework of ops of 'dev_infos_get' for both PF and VF

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

Returning redirection table size has been supported in ops of
'dev_infos_get' for both PF and VF. Default RX/TX configurations
of VF can be returned in ops of 'dev_infos_get', while it was
missed before.

v2 changes:
* Put getting reta size of both i40e PF and VF into a single patch.

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.
