In the current implementation, if Slirp tries to send an IP packet to a client with an unknown hardware address, the packet is simply dropped and an ARP request is sent (if_encap in slirp/slirp.c). With this patch, Slirp will send the ARP request, re-queue the packet and try to send it later. The packet is dropped after one second if the ARP reply is not received.
