Zhang, Helin Oct. 31, 2014, 9:03 a.m. UTC 
  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.
