>Environment:
AlphaStation 200
>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

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