The problem is we haven't finished transferring all the functions from the regular filters to the generic filters.
For example, igb, fm10k and enic haven't support generic filters yet. Ixgbe and i40e have supported the basic functions, but some advance features are not transferred to generic filters yet.
Seems it's not the time to remove the regular filters. Yong, I suggest to support both generic filter and regular filter in parallel.
So, we need to announce ABI change for the regular filter, until someday we remove the regular filter API.
