of course.  :)

i'm trying to manufacture arp packets that will trigger the kernel
message, so whether or not they'd normally be sent isn't an issue.

also note that i'm *not* trying to make the machine in questions crash
(although indeed it might as a result of the changes i've made), just
spew the message.

so...if i send a reply to my machine at from,
it should get a warning printed, yesh?
