Yep - you're right. The netmask *can't* mean anything when you're talking
point-to-point. A point-to-point is by definition an interface with a
mask of 0xffffffff and an automatic routing table entry (the other side).
Maybe the point-to-point interfaces themselves should fail to configure
if you try to give them a netmask or broadcast address !
Soooooo, *everyone's* making sense :)
