>Description:
	ipfilter (specifically, fr_makefrip()) is not robust against
	unaligned IP headers.  When used on an Alpha, this can lose --
	particularly in the case of if_ray with link0 set (for Windows
	compatibility), which always misaligns IP packets.

>How-To-Repeat:
	Run ipfilter on your Alpha, and configure it for Windows
	compatibility.

>Fix:
	Non provided.
