in 4 byte chunks. It turns out that with the 82c169C on the Netgear
FA-310TX Rev D2, if you tell the chip you have reserved a buffer of 1518
bytes, it will actually treat it as 1516 bytes since 1518 is divisible
by four. Consequently, a packet of 1514 bytes will always end up consuming
two buffers: the last coupleof bytes will spill over into the next
descriptor. This causes the pn_rx_bug_war() routine to trip unnecessarily.
I'm not sure if the 82c169B or 82c168 chips behave the same way; I'll
have to check them. In any case, this change should work just as well
with them. Note that the FA-310TX Rev D2 also has a Broadcom PHY
instead of a Level One LXT970 PHY, however this shouldn't make any
difference as far as the driver is concerned.
This change also allows me to do a way with one rounding overation in
pn_rx-buf_war().
vinum_init(): Change name of variable plexindex to objindex, which
better describes its purpose.
initsd(): Add a second parameter to determine whether it should wait
for completion or not. This allows it to DTRT when called
with the -w flag either directly or via initplex().
Add 'setstate' command (function vinum_setstate ()) to implement the
VINUM_SETSTATE_FORCE ioctl for diddling individual object states.
This is a repair tool which can also be used for panicing the system.
Use with utmost care if at all.
Add unimplemented commands 'checkparity' and 'rebuildparity'. Watch
this space.
initialized subdisks.
Tidy up some comments.
Eliminate sddownstate(); it wasn't being used any more. Return
REQUEST_DOWN instead.
Add setstate_by_force() to implement the VINUM_SETSTATE_FORCE ioctl
for diddling individual object states. This is a repair tool which
can also be used for panicing the system. Use with utmost care if at
all.
avoids a race condition where multiple RAID-5 subdisks are being
revived at the same time. The locks should also prevent conflicts
with user requests on concatenated and striped plexes, but this needs
more work.
Tidy up some comments.
are still converted to u_long by assignment of the uintptr_t, and
address calculations are still done using u_long. This is OK for
currently supported machines, but addresses should be represented
by vm_offset_t or uintptr_t in case pointers are longer than longs.
"Fixed" size of linker_path[]. MAXPATHLEN + 1 was 1 too large for
search paths with only one file path in them, but much too small
for search paths with several long file paths in them.
stuff from mem.c. If PERFMON is there, it will "steal" a minor from
mem.c, but mem.c doesn't need to know about this.
Fixed type of cmd argument in perfmon_ioctl().
Diskslice/label code not yet handled.
Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)
Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw
registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().
The lock structure cannot be the first element of the vm_map
because this can result in livelock between two or more system
processes trying to kmem_alloc_wait.

Trimble OEM Ace-II receiver. Low cost PCB with single
voltage input, external active antenna and two serial
ports with either NMEA and ITAPs output. Programmable
to be tuned for 'time' accuracy in fixed station config.
