clears out the transmit queue and zeroes the downlist pointer register,
but xl_txeof() isn't called before xl_start() tries to queue more packets,
xl_start() will think that the DMA is still in progress and not update
the downlist register again, thus causing packets to sit in the transmit
queue forever.

- Correctly observe the variable `extra_history_size' when changing
the size of history (scroll back) buffer.
- Added sc_free_history_buffer().

get a list of interfaces, and then automatically configure them if
${ifconfig_${ifn}} or /etc/start_if.${ifn} exists.
This makes it a lot easier to deal with machines that constantly change
their network configuration as you can leave ifconfig settings for all
the possible cards - just the ones that are present will be configured.

lines longer).
This application is in need for general code reformatting and warning
fixes.

support. I've been building world with these changes for months w/o
ill effect. I've also managed to build the cross tool chain for MIPS
with these patches.
Please note that the extent to which these patches work is largely
dictated by how well our tool chains support the cross compilation.
Building alpha binaries on i386 doesn't work. Supposedly building
i386 binaries on alpha does work, but I've not verified it with these
patches, however.
and set it to "/etc/pccard.conf.sample" in /etc/defaults/rc.conf.
Perhaps this default value can be inappropriate,
but I set to this value for the convenience of PC-card boot.flp users.
Please correct it if there are better solutions.
bit preliminary. It still returns an old-style code arg if SA_SIGINFO
is not set, but I'm not sure of the value of this since the traditional
bsd-style fourth argument (address) is missing.
Also, tidy up a bit of lint.
than a review, this was a nice puzzle.
This is supposed to be binary and source compatible with older
applications that access the old FreeBSD-style three arguments to a
signal handler.
Except those applications that access hidden signal handler arguments
bejond the documented third one. If you have applications that do,
please let me know so that we take the opportunity to provide the
functionality they need in a documented manner.
Also except application that use 'struct sigframe' directly. You need
to recompile gdb and doscmd. `make world` is recommended.
Example program that demonstrates how SA_SIGINFO and old-style FreeBSD
handlers (with their three args) may be used in the same process is at
http://www3.cons.org/tmp/fbsd-siginfo.c
Programs that use the old FreeBSD-style three arguments are easy to
change to SA_SIGINFO (although they don't need to, since the old style
will still work):
Old args to signal handler:
void handler_sn(int sig, int code, struct sigcontext *scp)
New args:
void handler_si(int sig, siginfo_t *si, void *third)
where:
old:code == new:second->si_code
old:scp == &(new:si->si_scp) /* Passed by value! */
The latter is also pointed to by new:third, but accessing via
si->si_scp is preferred because it is type-save.
FreeBSD implementation notes:
- This is just the framework to make the interface POSIX compatible.
For now, no additional functionality is provided. This is supposed
to happen now, starting with floating point values.
- We don't use 'sigcontext_t.si_value' for now (POSIX meant it for
realtime-related values).
- Documentation will be updated when new functionality is added and
the exact arguments passed are determined. The comments in
sys/signal.h are meant to be useful.
