PR #kern/600: PPP does not pay attention to IPTOS_LOWDELAY
Kernel PPP doesn't pay attention to IPTOS_LOWDELAY, but uses
a table of port numbers, which isn't a generic method. The following
patch fixes this (the table is still used, but in addition
PPP queues the packet in fastq if IPTOS_LOWDELAY is set.
