This patch implements feature, which allows user to change
input set mask for flow director using side-band channel.
This patch adds definition of FLOW_TYPE_MASK into the header file.
With this patch, user can now specify less than 4 tuple(src ip, dsp ip,
src port, dst port) for flow type TCP4/UDP4.

If you want to do this, you have to define the semantics generically
in include/uapi/linux/ethtool.h so that other drivers can implement
this too.
Please don't ever implement private, driver specific, interpretations
of the generic ethtool facilitites.
The semantics and interpretations of the values must absolutely be
consistent across all drivers in the tree.
Otherwise the user experience is terrible.
Thanks.
This is not new feature implemented in i40e driver. This is the original
feature of ethtool which allows user to specify subset of tuple for
setting up flow director.
i40e driver using it same way as ixgbe.
Please let us know if I misinterpreted your response.
Would you recommend that we re-submit patch with better patch
description (indicating that it is not new feature but just enabling
feature).
Thanks,
