+Subject: [PATCH] Update qperf.c
+
+Current version of qperf throws errors in environment with only ipv4 address
+
+        With ipv6.disable in kernel command line :
+
+        # qperf
+        unable to bind to listen port
+
+        strace :
+    9052  14:24:36.118470 socket(AF_INET6, SOCK_STREAM, IPPROTO_TCP) = -1 EAFNOSUPPORT (Address family not supported by protocol) <0.001313>

+    9052  14:24:36.120060 +++ exited with 1 ++
+
+        With qperf version 0.4.9 we defined AI_FAMILY as AF_UNSPEC, starting
+        qperf 0.4.11 the same is changed to AF_INET6 which causes issues
+        when ipv6 is disabled at protocol layer (as a kernel command line
+        arguement). This patch reverses the behavior.
