Any chance we will see Marcelo's work (or a derivative) commited to base?
Are there serious implications or potential side effects on adding it?

Its useful in proxy and voip environments and is also good for input
normalization when you need to set some ToS bit to normal when its coming
modified from Internet into your network.

Thank you.
