+Control whether the system attemps path-MTU discovery using RTP packets
+transmitted over IPv4.  (This is not configurable in IPv6.)  Possible values

+.RS
+.TP
+.B default
+Do whatever the kernel usually does with UDP packets.  This is, err, the
+default.
+.TP
+.B yes
+Force path-MTU disocvery.  The `don't fragment' bit is set on outgoing packets
+and we assume that the kernel will handle ICMP `fragmentation needed' errors
+coming back and fragment accordingly.
+.TP
+.B no
+Disable path-MTU discovery.  Packets will be sent without the `don't fragment'
+bit, and routers will be expected to fragment packets as necessary.
