for nodes hanging off of Central (untested), FireHose (untested) and
PCI (tested) busses.
- Add an additional parameter to OF_decode_addr() which specifies the
index of the register bank to decode.
These should allow to eventually add support for the Z8530 hanging off of
FireHose to uart(4) and to write support for PCI-based graphics adapters.

o Add a fallback location for the MAC address. Most of the early ne2000
PC Cards were built from the same parts, so most of them have the same
address in the CIS to grab the MAC from. Use this address as our
fallback if we don't find anything better.
o Add printf, in bootverbose, noting the MAC addresses that we find along
the way.
# Better sanity checking of the MAC address is needed. Will have to
# investigate using/creating a centralized function to do this as a number
# of other PC Card drivers each have their own ad-hoc tests.
a definite setup was broken: two ng_ksockets are connected to each other,
connect()ed to different remote hosts, and bind()ed to different local
interfaces. In this case one ng_ksocket is fooled with tag from the other
one.
Put node id into tag. In rcvdata method utilize tag only if it has our
own id inside or id equals zero. The latter case is added to support
packets send by some third, not ng_ksocket node.

1. Dependency on netgraph module was broken (wrong version).
2. Netgraph node type was never destroyed on unload. This
was masked by problem #1.
Fixed both by using NETGRAPH_INIT(). Now netgraph node type
is created on module load, as in the rest of netgraph modules.
This information will be very useful for people who are tuning applications
which have a dependence on IPC mechanisms.

at some offset. Unlike newer cards, the MAC address wasn't part of
the CIS as a specific FUNCE. These older cards were having their MAC
address show up as 0:2:4:6:8:a because that's what's in the ROM
locations that would be there in a real ne2000.
This patch allows one to specify the offset for the MAC address for
these cards. Specify one for the IBM Ethernet II card, as it is one
that has this problem. One shouldn't specify this unless the MAC
address really isn't in the CIS at all.
Side note: The novell probe likely shouldn't read the MAC address, and
that should be moved to the bus specific attach routine(s), maybe as a
convenience function in if_ed_novell.c.
My IBM Ethernet II (aka Info Mover) now has a believable MAC address.

suid application. The problem is that Linux applications using old Linux
threads (pre-NPTL) use signal 32 (linux SIGRTMIN) for communication between
thread-processes. If such an linux application is installed suid or sgid
and security.bsd.conservative_signals=1 (default), then permission will be
denied to send such a signal and the application will freeze.
I believe the same will be true for native applications that use libthr,
since libthr uses SIGTHR for implementing conditional variables.
