[1/2] 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.

I don't know examples when the information is required, but can imagine.

We have only 2 acks but as they are simple new fields,
better to announce their addition in advance and allow for more
discussion during 19.11 release cycle.

Applied (only patch 1 of 2)
