I will hire you to help me; I need the following to be done in
my net device driver:
With the ARP disabled (this is well documented so I believe I've done that),
while queueing the physical output, I need to get hold of the IP address
of where the packet is being sent. Yes, I mean IP address, not
Ethernet address, and yes this is not the destination addresses in
the IP header.
can you not use the routing table ? In a normal setup, either the
network part of your destination IP matches the network part of a
directly connected network and the address your are looking for is the
destination IP in the packet or it does not match and the next IP is the
IP of the gateway found by routing.
Is it what you are looking for ?
