the destination represents. For IP:
- Iff it is a host route, RTF_LOCAL and RTF_BROADCAST indicate local
(belongs to this host) and broadcast addresses, respectively.
- For all routes, RTF_MULTICAST is set if the destination is multicast.
The RTF_BROADCAST flag is used by ip_output() to eliminate a call to
in_broadcast() in a common case; this gives about 1% in our packet-generation
experiments. All three flags might be used (although they aren't now)
to determine whether a packet can be forwarded; a given host route can
represent a forwardable address if:
(rt->rt_flags & (RTF_HOST | RTF_LOCAL | RTF_BROADCAST | RTF_MULTICAST))
== RTF_HOST
Obviously, one still has to do all the work if a host route is not present,
but this code allows one to cache the results of such a lookup if rtalloc1()
is called without masking RTF_PRCLONING.
surprising how many trivial errors there have been... :-)
Some more cleanup is needed, but i'd like to separate the Lite2 changes
from other work, that's why this goes into a different commit.
People with serial printers should see whether i have broken the stty-
style printcap options (i hope not).

COMPAT_43 cruft. This is supposedly the last core utility that has
been using it! (So now, one should be able to remove this option from
the config files. Be aware that the last officially released xterm
however still requires it.)
The getty has been running now for several weeks on my modem line, so
i feel safe about it.
Obtained from: mostly from the NetBSD vendor-branch
it empties all of the 256 byte incoming fifo, as it can spend more time
processing one port than intended, especially if data is streaming in
at 115.2K. The port fifo will be emptied and dumped into the tty system
and left until next time. I've been running this for quite some time on
one of my systems here.
Also, if the tty layer is blocked or full it lets the hardware assert the
flow control rather than loosing the data.
In a nutshell, this macroizes the local/global symbol scoping rules
that are different in a.out and ELF. It also makes the i386 assembler
stubs conform to i386 PIC calling conventions - the a.out ld.so didn't
object, but the ELF one needs it as it implements PIC jumps via PLT's as
well as calls. The a.out rtld only worked because it was accidently
snooping the grandparent calling function's return address off the stack..
This also affects the libc_r code a little, because of cpp macro nesting.
These binary files most definately do not come under /usr/share's
"architecture independent text files" rule... even though these same
images would be used on other processors with pci architectures.
Compile for FreeBSD-2.2
Fix some compile warnings about function declarations
-current's VM include files have changed lately, this needed to be updated.
Use correct major number.
This is now two seperate drivers that support (I think) all of Stallions's
range, including the high performance intelligent cards, and their older
cards.
