ARP_QUEUE_LEN limits the maximum buffers on one (unresolved) entry. In
addition, the default
setting is to queue 1 entry only (when ARP_QUEUEING==0). The problem you
describe results
from poor protocol design, anyway: you should first check if you can reach the
remote side
before trying to flood the network with packets ;-)
