> 
> 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.
