Should it be then two patches? First patch to split fdir and hash input set configuration and then second one to remove existing functionality? At the moment it is not obvious that this patch not just splits fdir input set configuration but removes some features in a way that fdir it is not compatible with DPDK 2.2 anymore.

I do not have a problem with selecting it at the same time - it always was this way with the legacy systems. But now new NIC supports new way of configuring input set with flexible payload as a part of this input set. So why not to have new way of configuration available as well and change input set using one API call instead of splitting single configuration in to two parts?
