This series adds the ability, for crypto PMDs, to communicate the
minimum head/tailroom requirement it may have, using the existing
cryptodev_info framework.

The availability and use of head/tailroom is an optimisation if the
hardware supports its use for crypto-op info. Devices that do not
support using the head/tailroom, can continue to operate without
any performance-drop.

Cavium's OcteonTX crypto hardware supports this feature and would use
headroom and tailroom for submitting crypto-ops to the hardware.

* Removed deprecation notice and updated release notes
* Added corresponding change in test-cryptodev

Anoob Joseph (3):
  cryptodev: add min headroom and tailroom requirement
  app/crypto-perf: honour cryptodev's min headroom/tailroom
  test/crypto: skip validation of head/tailroom used by PMD
