In a previous message I described a problem with Linux PLIP and a DOS
program (JNOS), perhaps other DOS tcp/ip programs are affected, I don't
know.

I fixed it by commenting out 

dev->rebuild_header  = plip_rebuild_header; 

in plip_init() so it would use the default eth_rebuild_header, which 
takes care of arp.

the programs that were working before this change still work, and
now JNOS works.

Is there a reason for plip_rebuild_header()? Why not use the defaults,
this would actualy make the code smaller. 

BTW, why doesn't tcpdump (v 3.0) work with plip devices, it used to.
Do I need a new tcpdump?
