rdma: api: prepare support for direct verb
Prepare rdma interface creation API for direct verb support:
- add new optional 'mode' parameters to select between ibverb or direct
verb backend (optional, default to 'auto')
- set default value for rxq_num (1), rxq_size (1024) and txq_size
(1024) so they are now optional
- bump default create value for rxq_size and txq_size to 1024 if
unset (0) so they are coherent with default values above
Type: feature
