o Introduce private types for use in linux syscalls for two reasons:
1. establish type independence for ease in porting and,
2. provide a visual queue as to which syscalls have proper
prototypes to further cleanup the i386/alpha split.
Linuxulator types are prefixed by 'l_'. void and char have not
been "virtualized".
o Provide dummy functions for all syscalls and remove dummy functions
or implementations of truely obsolete syscalls.
o Sanitize the shm*, sem* and msg* syscalls.
o Make a first attempt to implement the linux_sysctl syscall. At this
time it only returns one MIB (KERN_VERSION), but most importantly,
it tells us when we need to add additional sysctls :-)
o Bump the kenel version up to 2.4.2 (this is not the same as the
KERN_VERSION MIB, BTW).
o Implement new syscalls, of which most are specific to i386. Our
syscall table is now up to date with Linux 2.4.2. Some highlights:
- Implement the 32-bit uid_t and gid_t bases syscalls.
- Implement a couple of 64-bit file size/offset bases syscalls.
o Fix or improve numerous syscalls and prototypes.
o Reduce style(9) violations while I'm here. Especially indentation
inconsistencies within the same file are addressed. Re-indenting
did not obfuscate actual changes to the extend that it could not
be combined.
NOTE: I spend some time testing these changes and found that if there
were regressions, they were not caused by these changes AFAICT.
It was observed that installing a RH 7.1 runtime environment
did make matters worse. Hangs and/or reboots have been observed
with and without these changes, so when it failed to make life
better in cases it doesn't look like it made it worse.
the cwd is looked up inside the kernel. The native getcwd() in libc
handles this in userland if __getcwd() fails.

blown over by the Hurricane and had a house dropped on you by the Tornado.
Now it's time to have your parade rained on by... the Typhoon!
This commit adds driver support for 3Com 3cR990 10/100 ethernet
adapters based on the Typhoon I and Typhoon II chipsets. This is actually
a port of the OpenBSD driver with many hacks by me.
No Virginia, there isn't any support for the hardware crypto yet. However
there is support for TCP/IP checksum offload and VLANs.
Special thanks go to Jason Wright, Aaron Campbell and Theo de Raadt for
squeezing enough info out of 3Com to get this written, and for doing
most of the hard work.
Manual page is included. Compiled as a module and included in GENERIC.
it may be plugged into a kernel that supports VLANs. If the kernel is
not VLAN aware, things will still work as before.
Modules don't really have option support, so this is somewhat of a hack.
- All sources are built in a single object, reducing namespace pollution.
- Kill the ready queue, and handle a busy response to mly_start in callers
rather than deferring the command.
- Improve our interaction with CAM:
- Don't advertise physical channels as SCSI busses by default.
- use the SIM queue freeze capability rather than queueing CDBs internally.
- force bus reprobe at module load time.
- Clean up more resources in mly_free.
- Tidy up debugging levels.
- Tidy up handling of events (mostly just code cleanliness).
- Use explanatory macros for operations on bus/target/channel numbers.
- Move the lance_probe function to if_lnc.c.
- Support C-NET(98)S again.

a KLD. Still doesn't work well except in the PCMCIA case (now if only
pccardd(8) could load and unload drivers dynamically...). Mainly, it
tries to find fdc0 on the PCI bus for whatever obscure reasons, but i
need someone who understands driver(9) to fix this. However, it's at least
already better than before, and i'm tired of maintaining too many private
changes in my tree, given the large patches bde submitted. :)
Idea of a KLD triggered by: Michael Reifenberger <root@nihil.plaut.de>
could only get a chance of testing it under 4.3, but together with the
if_oltr.c fixes at least it seems to work now. If someone has the chance
to test this under -current, please do.
Unfortunaltey, the TR code itself (if_iso88025subr.c) is not written
in a way that would allow to make a seaparate KLD out of it. By now,
just link it directly into the oltr KLD since it's probably the POLA
to be able to load the TR code together with the only TR hardware
driver we've got by now.
I've got one single unexplained panic (in doreti_switch or somewhere
there, calling a 0xc1XXXXXX address that did no longer belong to the
kernel at all) after unloading the modules once, thus i don't propose
a MFC of this module despite my testing has been done solely on 4.3,
unless someone is really going to test this stuff in -current.
gigabit ethernet controller chip. This device is used on some
fiber optic gigE cards from SMC, D-Link and Addtron. Jumbograms and
TCP/IP checksum offload on receive are supported. Hardware VLAN
filtering is not, because it doesn't play well with our existing
VLAN code. Also add manual page.
There is a 4.x version of this driver available at
http://www.freebsd.org/~wpaul/Level1/4.x if anyone feels adventurous
and wants to test it. I still need to do performance testing and
tuning with this device.
(For my next trick, I will make the 3Com 3cR990 sit up and beg.)
