Hi,

I just noticed support.S has some functions that are never called,
namely insque() and remque(). We only had one consumer of these
functions (netipx), but it used an inlined version of this function. I
haven't tested this patch, but I don't have any reason to believe it
breaks stuff.

Anyway, I'm just sending this patch to you folks. Have fun with it! ;-)
