From 1ab74cea060d776b19857c3babc64d729bbdba5c Mon Sep 17 00:00:00 2001 From: Fabien Chouteau Date: Mon, 1 Aug 2011 18:18:37 +0200 Subject: Delayed IP packets 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.
