[PATCH libibverbs v2] Add basic man page entry for ibv_xsrq_pingpong

[Jarod Wilson <jarod-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

We have internal tools that complain about any binaries that are missing
corresponding man pages, and all the other examples have 'em.

Shamelessly ripped off from ibv_srq_pingpong's man page.

+
+.SH DESCRIPTION
+.PP
+Run a simple ping-pong test over InfiniBand via the extended reliable
+connected (XRC) transport service, using a shared receive queue (SRQ).
+
+.SH OPTIONS
+
+.PP
+.TP
+\fB\-p\fR, \fB\-\-port\fR=\fIPORT\fR

+use IB device \fIDEVICE\fR (default first device found)
+.TP
+\fB\-i\fR, \fB\-\-ib\-port\fR=\fIPORT\fR
+use IB port \fIPORT\fR (default port 1)
+.TP

+ping-pong messages of size \fISIZE\fR (default 4096)
+.TP
+\fB\-m\fR, \fB\-\-mtu\fR=\fIMTU\fR
+use path mtu of size \fIMTU\fR (default 2048)
+.TP
+\fB\-c\fR, \fB\-\-clients\fR=\fICLIENTS\fR

+.TP
+\fB\-l\fR, \fB\-\-sl\fR=\fISL\fR
+use \fISL\fR as the service level value (default 0)
+.TP
+\fB\-e\fR, \fB\-\-events\fR

+
+.SH BUGS
+The network synchronization between client and server instances is
+weak, and does not prevent incompatible options from being used on the
+two instances.  The method used for retrieving work completions is not
+strictly correct, and race conditions may cause failures on some
+systems.
