* bumped default TCP send/recv buffer to 128K (this is not the kernel buffer
that controls the window, but rather the Iperf internal buffer)
* update autoconf goo using Autoconf 2.65, this should help portability a bit
* honor -i flag when for a server (-s) when using TCP
* Exit rather than warn on connection failure
Iperf is a tool for measuring TCP and UDP bandwidth performance.
It reports bandwidth, delay jitter, datagram loss. It also supports
