About the features called flow director, filtering or flow steering,
we have some overlap in our API that we should clean.
It is especially important when considering to freeze the API for stability.
Please read this deprecation notice from December 2016:
* ethdev: the legacy filter API, including
``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
PMDs that implement the latter.
Target release for removal of the legacy API will be defined once most
PMDs have switched to rte_flow.
We must mark the eth_dev_filter API as deprecated and decide about
a date to remove it.
Which PMD is implementing this API and not rte_flow?
In accordance with feature matrix is it i40e_vec, ixgbe_vec and qede, but
I think it is just a mistake in documentation.
Flow API support tick is missing for many PMDs which actually implement
(as far as I can see): bonding, dppa2, e100, mlx4, qede, mvpp2, softnic.
I've added maintainers to CC.
If there are still some, deadlines should help them to be converted :)
If some help is needed, please ask.
Anyway, after more than 2 years of notice, I think it is fair to mark
the legacy API as deprecated in 19.05 release.
I agree. I think it is a good idea.
Andrew.
