I discovered a difference between the 2.1.7 and 2.2 tcp/ip stack that
I cannot explain.
If I have a host in a subnetted C-net, say 192.1.1.0/28
and I send an icmp echo request to the broadcast address of the C-net
(so NOT to 192.1.1.15) the 2.1.7 stack does send an echo reply
but the 2.2 stack does not.
So an all-subnets directed broadcast seems to be ignored on 2.2
stacks...I think this broken, yet fail to see where it was broken.
