With 2.4.2-ac7, unpatched? Wrong log was with 2.4.2-ac7 with Arnaldo patch,
or with && 0?

Yes, that's wrong. Packet sent to 001D8022 with 001D8022 in visited nets.
It is 2.4.2-acX bug...

But why on earth you are sending them? You must received this frame
(starting FF FF 00 50 00 14 ...) from someone? Maybe ipxdump does not
handle outgoing packets while tcpdump does not print incoming one?

Where they appear? Same for rest of file. Does anybody have idea
why we do not have incoming packets logged here? They have ipx_tctrl
01, so they were routed by kernel - so they must be routed from somewhere,
no?
