In 2005, TC_RED_HARDDROP kernel support was added to RED and GRED

current iproute2 doesnt have user land support.

Is there some patch waiting somewhere, or should we :

- Remove kernel support, since nobody uses it.

- Add iproute2 support.

I used it in a project which configured the GRED qdisc directly from
the application.

I thought I added iproute2 support back then but obviously must have
missed it or the patch got lost. I'll send a patch to Stephen.
