From aad1239a7e15f42c0b8a802433582c48417a4541 Mon Sep 17 00:00:00 2001 From: Sebastian Ottlik Date: Wed, 2 Oct 2013 12:23:15 +0200 Subject: [PATCH] slirp: call socket_set_fast_reuse instead of setting SO_REUSEADDR SO_REUSEADDR should be avoided on Windows but is desired on other operating systems. So instead of setting it we call socket_set_fast_reuse that will result in the appropriate behaviour on all operating systems.
