It is getting messier! [1]

Hi Thomas,

Any suggestion on how to manage these rte_flow patches, we are late and they
aren't settle down yet. There are some level of dependency and there are some
uncertainty in some of the dependent patches because of ABI/API process.

It would be great to get them incremental or have a plan to how to proceed.

Previous version in this thread is following patches:
[PATCH v4 1/2] ethdev: add supported hash function check
[PATCH v4 2/2] app/testpmd: new parameter for port config all rss command

And this set is:
[PATCH v5 1/2] ethdev: introduce generic IP/UDP tunnel checksum and TSO
[PATCH v5 2/2] app/testpmd: testpmd support Tx generic tunnel offloads

But there is already v5 send for this set and in other thread there is v7 of it:
[PATCH v7 0/2] support Tx generic tunnel checksum and TSO
[PATCH v7 1/2] ethdev: introduce generic IP/UDP tunnel checksum and TSO
[PATCH v7 2/2] app/testpmd: testpmd support Tx generic tunnel offloads

Most probably you have intended to send another patchset here.
