+* ethdev: The deprecated function ``rte_eth_dev_count`` was removed.
+ The function ``rte_eth_dev_count_avail`` is a drop-in replacement.
+ If the intent is to iterate over ports, ``RTE_ETH_FOREACH_*`` macros
+ are better port iterators.
+
+* ethdev: RTE_FLOW_ITEM_TYPE_META data endianness altered to host one.
+ Due to the new dynamic metadata field in mbuf is host-endian either, there
+ is the minor compatibility issue for applications in case of 32-bit values
+ supported.
+
+* ethdev: the tx_metadata mbuf field is moved to dymanic one.
+ PKT_TX_METADATA flag is replaced with PKT_TX_DYNF_METADATA.
+ DEV_TX_OFFLOAD_MATCH_METADATA offload flag is removed, now metadata
+ support in PMD is engaged on dynamic field registration.
