>> Nope. Propose a generic netlink API, probably as an extension to ethtool, which other vendors can use as well.

ACK,  will remove DMAC filters debugfs from this patch set and will submit this change with netlink API in separate set.

This is exactly Jakub and my point. Is your hardware so special it does things which no other vendor does? Is the concept of DMAC filters dropping packets unique to your hardware? Is this feature so obscure that no other vendor will ever implement it? And if it is that obscure, is any user actually going to use it?
