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 CPT hardware supports this feature and would use headroom and tailroom for submitting crypto-ops to the hardware.
