There are three cases of drivers using fdir: - simple ones which are just borrowing things like rte_filter_type addressing these is trivial; mostly just keep rte_filter_type for now - Intel ones like i40e and ixgbe which still expose fdir api's. Can deprecate the PMD API's and move the fdir structures into intel commonc code. - drivers where fdir was used in variable names but never really used the infrastructure. Will have proposed patches in a few days.
