Helo.

I have for a couple of days tried to learn dhcpd to work with multiple
interfaces on Aix. I have found out that both aix and dhcpd support
multiple networking api's and have tried different ones. Aix dlpi is just
too damaged to bind to one interface, and bpf lacks the support of
sending packages.
That's when i found out about NDD (Socket Addresses in the Operating=20
System Network Device Driver ) that works kinda like bpf sending and
modified the bpf-code to use NDD to send packets.

And... It works. Wonderful.

Here comes two patches, One to fix macro-guards for one header file and
the other one is the bpf+ndd patch for aix. The bpf+ndd code is not as
generic as most of you probably would like it to be but it works =3D) , and
it is a good start to supporting multiple interfaces under aix.

All testing and devel has been done under aix 5.1, and just light testing
under aix 5.3.

Look at the code and provide feedback how it's supposed to be
implemented. If testing is needed and testcases need to be done I could
gladly do that to get the code accepted.
