doc: announce ethdev ABI change for LRO fields

It may be needed by the user to limit the LRO session packet size.
In order to allow the above limitation, a new Rx configuration may be
added for the maximum LRO session size.

A new capability may be added too to expose the maximum LRO session size
supported by the port.

   This scheme will allow PMDs to avoid lookup to internal ptype table on Rx and
   thereby improve Rx performance if application wishes do so.
 
+* ethdev: New 32-bit fields may be added for maximum LRO session size, in

 * cryptodev: support for using IV with all sizes is added, J0 still can
   be used but only when IV length in following structs ``rte_crypto_auth_xform``,
   ``rte_crypto_aead_xform`` is set to zero. When IV length is greater or equal
