+1 Agree with you :)

The goal of this RFC proposal is to see how to progress on API cleanup.
There are actually 2 parts:
1/ The flow director functions of rte_ethdev.h were only used for enic in
DPDK 2.0. We could set a deprecation notice to remove them in DPDK 2.2.
2/ Some associated structures are also used for rte_eth_conf.
My question was to check how it would be relevant to remove this rte_fdir_conf.
