Hi all,

we have the following deprecation waiting for more than 2 years already:

* ethdev: The flow director API, including ``rte_eth_conf.fdir_conf`` field,
  and the related structures (``rte_fdir_*`` and ``rte_eth_fdir_*``),
  will be removed in DPDK 20.11.

I think 2 years is more than enough for maintained drivers to care about it.
So, I'm going to process the deprecation in 22.11 release cycle and apply
removal including affected code in drivers.

Andrew.
