Add updates noting that the BPF devices and BPF driver might not exist
until you run AIX's tcpdump at least once.

+ Note that the BPF driver and the "/dev/bpf" devices might not exist

+ the devices if they don't already exist. Our libpcap doesn't create
+ them, so you should run (as the super-user) AIX's tcpdump once (you
+ can interrupt it as soon as it starts capturing packets) to create
+ the devices. Do this before running the configure script, so that
+ the configure script finds the BPF devices and chooses to configure
+ libpcap to use BPF.
+
+ It may be that you will need to do this after every reboot; we don't
+ know whether that's the case, and, if it is the case, don't know
+ whether there's a way to force the driver to be loaded on a reboot.
+ (We also don't know how to make libpcap create the devices and, if
+ necessary, load the driver.)

compiles but fails to work correctly, send us as detailed as
possible a description of the symptoms, including indications of the
