In iso88025_ioctl you must check that they have not exceeded ISO88025MTU (or absolute max) and then in the interface ioctl ex tok_ioctl that they have not exceeded the cards capacity. Actually I think that is reversed :) On another note, could you look at my code for iso88025_ioctl it is panic'ing when I set the ip address or netmask, oops.
