> This patch introduces a fdir flow management for guaranteed/shared
> space tracking.
> The fdir space is reported by the
> i40e_hw_capabilities.fd_filters_guaranteed and fd_filters_best_effort.
> The fdir space is managed by hardware and now is tracking in software.
> The management algorithm is controlled by the GLQF_CTL.INVALPRIO.
> Detailed implementation please check in the datasheet and the
> description of struct i40e_fdir_info.fdir_invalprio.
> 
> This patch changes the global register GLQF_CTL. Therefore, when devarg
> ``support-multi-driver`` is set, the patch will not take effect to
> avoid affecting the normal behavior of other i40e drivers, e.g., Linux
> kernel driver.
