Split the README items into "using BPF" and "using DLPI" items; if you can use BPF, you don't need to have the latest DLPI driver or make sure it's loaded (and maybe we're finally at the point where you can use BPF). Reformat a bit. Note that the DLPI support has problems with DL_PROMISC_MULTI failing.

Using BPF:
Note that we now attempt to work around AIX BPF's weirdness, indicate that there may be compile-time or run-time problems with the workarounds, suggest that people send in a detailed report and fall back on DLPI if they have those problems, and suggest that if they construct fixes for the problems they send them to patches@tcpdump.org. Fix the white space.

(1) AIX 4.x's version of BPF is undocumented and somewhat unstandard; the
current BPF support code includes changes that should work around
Add updates noting that the BPF devices and BPF driver might not exist until you run AIX's tcpdump at least once.

that; it appears to compile and work on at least one AIX 4.3.3
machine.
Note that the BPF driver and the "/dev/bpf" devices might not exist
on your machine; AIX's tcpdump appears to load the driver and create
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.)
(2) If libpcap doesn't compile on your machine when configured to use
BPF, or if the workarounds fail to make it work correctly, you
should send to tcpdump-workers@tcpdump.org a detailed bug report (if
the compile fails, send us the compile error messages; if it

compiles but fails to work correctly, send us as detailed as
possible a description of the symptoms, including indications of the
network link-layer type being wrong or time stamps being wrong).
If you fix the problems yourself, please send to patches@tcpdump.org
a patch, so we can incorporate them into the next release.
If you don't fix the problems yourself, you can, as a workaround,
make libpcap use DLPI instead of BPF.

This can be done by specifying the flag:
--with-pcap=dlpi
to the "configure" script for libpcap.

If you use DLPI:
(1) It is a good idea to have the latest version of the DLPI driver on
your system, since certain versions may be buggy and cause your AIX
system to crash. DLPI is included in the fileset bos.rte.tty. I
found that the DLPI driver that came with AIX 4.3.2 was buggy, and
had to upgrade to bos.rte.tty 4.3.2.4:

Alternatively, you can uncomment the lines for DLPI in
/etc/pse.conf and reboot the machine; this way DLPI will always
be loaded when you boot your system.

(3) There appears to be a problem in the DLPI code in some versions of
AIX, causing a warning about DL_PROMISC_MULTI failing; this might
be responsible for DLPI not being able to capture outgoing packets.
