_______________________________________________________
Details:
I propose to limit the ARP queue length, by ARP_QUEUE_LEN (defaults to 3).
This will make sure that if two IPs are unresolved, then the first one them
won't be able to "steal" all the MEMP_ARP_QUEUE objects, by limiting both
queues to ARP_QUEUE_LEN packets awaiting in each queue.
>From what I understand & tested, this will shouldn't hurt any higher level
(UDP, TCP, ICMP, applications, ...)
Patch included.
