From 72ac83e7f27f5956f1822382a299c0e75a65c9aa Mon Sep 17 00:00:00 2001 From: "Bruce A. Mah" Date: Wed, 12 Nov 2014 13:58:23 -0800 Subject: Make UDP tests honor the -w option for setting the socket buffer size. This appears to be necessary on some long, high-bandwidth paths to get sane results, either by reducing packet loss or by somehow allowing the sending host of a test to go faster.
