[dpdk-dev] [RFC PATCH] ethdev: remove old flow director API

[dpdk-dev] [RFC PATCH] ethdev: remove old flow director API

[Thomas Monjalon]

It's time to remove this old API.
It seems some work is still needed to rely only on eth_ctrl API.
At least ixgbe, i40e and testpmd must be fixed.
Jingjing, do you think it's possible to remove all these structures
from rte_ethdev.h?

Thanks

Why? I thought eth_ctrl API would be enough.
It seems strange to have a part of the flow director API in rte_eth_ctrl.h and
another part in rte_ethdev.h. Other filters have no impact on rte_ethdev.h.

rte_fdir_conf in rte_eth_conf is used when rte_eth_dev_configure to set initialization parameters which cann't be changed at running time.
For example, if we disable the flow director, we can set the mode in it to RTR_FDIR_DISABLE, then the resource will not be allocated for flow director.
The way is the same as rss_conf in rte_eth_conf. While the filter_ctrl can provide interface to configure parameters or add/delete rules at device running time.

NAK.

I'm certainly not opposed to removing the API's if they are truly no longer
needed.  But they have been codified as part of the ABI, so the deprecation
schedule needs to be followed.  Given what you've said above, it seems like that
might be worthwhile anyway, as it will provide the needed runway to allow users
to convert to the new API.

+1 NAK. Agree with Neil.

+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.
