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.
