Change 130758 by hselasky@hselasky_laptop001 on 2007/12/12 23:35:04

	
	It seems like there is a problem setting
	the MTU too high for the "if_ural" compatible
	chips. Try reducing the MTU size back to
	the original.
	
	Symptom: "real length" in the packet
	header was 0 while received packet
	length on the USB bus was non-zero.
	
	If this problem re-appears you can
	work it around by something like this:
	
	ifconfig ural0 mtu 1100 up
