[dpdk-dev] [PATCH v3 6/9] distributor: remove deprecated code

[Anatoly Burakov <anatoly.burakov@intel.com>]

From: Marcin Baran <marcinx.baran@intel.com>

Remove code for old ABI versions ahead of ABI version bump.

Signed-off-by: Marcin Baran <marcinx.baran@intel.com>
Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com>
---

Notes:
    v3:
    - Removed single mode from distributor as per Dave's comments
    
    v2:
    - Moved this to before ABI version bump to avoid compile breakage

- * processing, and may be optionally returned to the distributor via
- * the oldpkt parameter.
- * Unlike rte_distributor_get_pkt(), this function does not wait for a new
- * packet to be provided by the distributor.
- *
- * NOTE: after calling this function, rte_distributor_poll_pkt() should
- * be used to poll for the packet requested. The rte_distributor_get_pkt()
- * API should *not* be used to try and retrieve the new packet.
- *
- * @param d
- *   The distributor instance to be used
- * @param worker_id
- *   The worker instance number to use - must be less that num_workers passed
- *   at distributor creation time.
- * @param oldpkt
- *   The previous packet, if any, being processed by the worker
