since we have not requested locked vnode (LOCKLEAF is not used for namei()
call), the vnode is returned unlocked, so we need to use vrele(), not vput()
This fixes kern/11044.
- correct byte lifetime computation to conform to RFC2401 p23 (use
packet BEFORE compression)
- stabilize deflate calls
- present error messages better
that the page being zero'd was not completed and that page zeroing
should be aborted. This may be used by machine-dependent code doing
slow page access to reduce the latency of running a process that has
become runnable while in the middle of doing a slow page zero.
Ethernet chip, which is based on the SiS 900 core, but with differences
in the PHY and filter programming interface, and different WoL and
802.3x flow control programming.
This chip appears on new NetGear FA-312TX cards. Thank goodness
they're finally ditching the LiteOn chips.
support ipcomp ACQUIRE messages (again).
it violates RFC2367 slightly. RFC2367 does not suport ipcomp at all
so we have no choice.

do not leave dangling pointer after KFREE(). caused kernel panic with
certain PF_KEY message (error case) - only root can open PF_KEY socket
so it is not security issue.

Do away with nfs_writebp completely, it's not needed anymore.
Keep an eye on the range of a file that needs to be committed, and

that is not able to sync out a range of a file may elect to sync
the whole file anyway.

The VME2chip can use this to translate a VMEbus irq to a cpu irq.
The VMEchip (on mvme147) can't deal with the VMEbus irq and cpu irq
being different so we just panic in that case for now.
this avoids too aggressive memory usage on heavy load web server, for example.

(this happens if we connect to IPv4 mapped destination and then IPv6

provides some 44k of saving in code size on arm26. More savings, and some
documentation, are still to come.
respond in the allotted time if they're told to TALK immediately after
completing a LISTEN command. Experimentation with adb_op_sync() yielded
consistent results when the timeout was increased from the documented
6900 usec to 8000 usec, so we'll make that change here.
(Accurate and complete documentation of the hardware sure would help...)
and a front-end driver for the Ether3. Only semantic change is to remove
ea_claimirq() and ea_releaseirq() on the grounds that the seem too spurious
to warrant a callback to the front-end.
in the MIPS prom loader we have to be very careful how the sections are
ordered and the number of sections defined. For this reason the standard
linker scripts cannot be used.
The exact rules don't appear to be documented and a little experimentation
is required.
and alpha ports.
Uses PROM standalone I/O functions but due to the lack of a lseek function
it currently only works with version 5.40 of the firmware. A more portable
solution is being worked on.
installboot utility requires several changes in order to correctly install
the bootstrap code - there is a "volume directory" which contains a list
of filenames, start sectors and length. We need to add a "boot" entry of
the correct length starting at block 2. The boot file has to be ecoff
which means we waste another 0.5k
Normally the Mips filesystem has a ~500k partition for this purpose but it
should be possible to squeeze it all into the first 7k "BSD Style" (1k is
required for 2 different copies of the partition table)
Only the bootxx_ffs first stage bootstrap has been tested via bootp() which
loads the second stage off disk and then boots the kernel.

on prior to have syscall exception. MIPS1 assembler hook arranges
to enable the bit for its own. MIPS3 does the same effect by
turning off EXL bit.

and data cache sizes). R4000 uses 2^(12+IC) and 2^(12+DC). IDT32364
uses 2^(9+IC) and 2^(9+DC).
abstract around the problem by making the base a parameter to the
MIPS3_CONFIG_CACHE_SIZE macro. we pass the base down from mips_vector_init
to mips3_vector_init and to mips3_ConfigCache (where it is used).
XXX: someone with an MIPS3_4100 should switch to this and get rid
of the ugly ifdefs in cpuregs.h
VGA_CONSOLE_SCREENTYPE because the screen types are hardware specific

to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.
