Since ntuple rule insert and delete are part of ethtool, I thought having this config also in ethtool will make user life easy ie all ntuple related stuff within one tool. Thanks, Sunil.

Any further feedback or objections to these change ? Thanks, Sunil.
From: Sunil Goutham <sgoutham@marvell.com> Some NICs share resources like packet filters across multiple interfaces they support. From HW point of view it is possible to use all filters for a single interface. This 2 patch series adds support to modify ntuple rule count for OcteonTx2 netdev.
