Hi David,

Thanks for that.  Owe you a beer!

Thinking out loud, doesn’t this also require:

#include <linux/const.h>


Or at least iproute2 would need to know about _BITUL as it doesn’t at present.
Which also means iproute2’s Linux uapi shadow would also have to import
linux/const.h.  Or have I got wrong end of stick?

Cheers,

Kevin
