_______________________________________________________
Details:
If there's an unresolved entry (state=ETHARP_STATE_PENDING) this new code will
avoid sending a ARP request for each packet.
It will be limited for ARP_MAXPENDING (=10) seconds, and ARP packet will be
sent every ARP_TMR_INTERVAL (1 second).
When entry is unresolved (or expired after ARP_MAXAGE seconds), it wont ARP
flood the network anymore.
Patch included, and tested with ARP_QUEUEING enabled and without it.
