[PATCH v2 3/3] doc: announce change to LLDP packet detection in iavf PMD

[Ciara Loftus]

The iavf PMD transmit paths currently use two methods to
identify if an mbuf holds an LLDP packet: a dynamic mbuf
field and the mbuf ptype. A future release will remove the
dynamic mbuf field approach at which point the ptype will be
the only approach used.

 * bus/vmbus: Starting DPDK 25.11, all the vmbus API defined in
   ``drivers/bus/vmbus/rte_bus_vmbus.h`` will become internal to DPDK.
   Those API functions are used internally by DPDK core and netvsc PMD.
