* updated with the source MAC and IP addresses supplied in the packet.
* You may want to disable this if you do not trust LAN peers to have the
* correct addresses, or as a limited approach to attempt to handle
* spoofing. If disabled, lwIP will need to make a new ARP request if
* the peer is not already in the ARP table, adding a little latency.
* The peer *is* in the ARP table if it requested our address before.
* Also notice that this slows down input processing of every IP packet!
