I was going through the ARP implementation of XINU OS written by D
comer and i found that the design as one shared cache for entire
network interfaces. But the ARP implementation seems quite contrary.
As the ARP protocol is inside the device driver and hence each device
driver would contain a seperate ARP cache and thus I don't see ARP
cache as a global shared memory. But this would have been possible had
the ARP protocol reside inside the IP process or ARP as a seperate
process.

And I also don't see the ARP cache declared as global shared memory,
instead it is intialized in arpinit().

If i am wrong, please correct me.

I look forward to hear from you.

Thanks
