- Instead of hooking the handler on the specdev of a mounted file system
hook directly on the `struct mount'.
- Rename from `vn_cow_*' to `fscow_*' and move to `kern/vfs_trans.c'. Use
`mount_*specific' instead of clobbering `struct mount' or `struct specinfo'.
- Replace the hand-made reader/writer lock with a krwlock.
- Keep `vn_cow_*' functions and mark as obsolete.
- Welcome to NetBSD 4.99.32 - `struct specinfo' changed size.

IHAE "IP Header Alignment Enable" feature of RXC register;
- careful cross referencing at KSZ8692P/8841P/8842P PDFs indicates IHEA
bit works as follows; When the feature is turned on, Rx DMA engine
will populate Rx frame data in the Rx memory with +2 or +3 byte swifted
to make its IP head field 32bit aligned. The shift amount is recorded
inside RDES0 to tell 0, 2 or 3. The automatic alignment is done only
when IHAE is enabled _and_ the Rx frame was IP frame. In other cases,
RDES0 swift amount field keeps 0.
- KSZ8841P document mentions the IHAE bit but its reference link is broken
to tell the new RDES0 field. KSZ8842P lacks both. The bit usage of
RDES0 23:20 seems different from KSZ8692P, which brings me a vague
suspiction of documentation error.
envstat(8) and the envsys framework:
- Modify the ENVSYS_SETDICTIONARY ioctl to support the following
plist structure:
<dict>
<key>foo0</key>
<array>
<dict>
<key>index</key>
<string>sensor0</string>
<key>description</key>
<string>cpu temp</string>
...
Another property for this sensor
...
</dict>
...
Another dictionary for other sensor
...
</array>
...
Another device as above
...
</dict>
Multiple devices with multiple sensors can now be specified, that means
that to set the properties only one copyin(9) is needed now.
- Added the ENVSYS_REMOVEPROPS ioctl, that accepts a boolean object
"envsys-remove-props" and when set to true, all properties that were
set previously by ENVSYS_SETDICTIONARY will be removed. That means that
you can now set multiple critical limits, descriptions and all they
will be removed or changed to its default value (for rfact and
description objects).
- Added the 'index' and 'allow-rfact' objects into the sensor dictionaries,
for better interactivity with userland. To know the position of the
sensor and to know if sensor allows to change the rfact.
- Misc cosmetic changes for consistency.
- Use a two clause license for all my code.
at the same time and the code accessed to an unexistent dictionary:
- Rather than using a global dictionary, use a singly linked list to
access to the dictionaries, one per event.
- When the dictionary has been sent to userland, destroy it and remove
it from the list.
With that change it is possible to receive multiple events at the
same time without panics; again thanks to rmind@ for comments and help
with locking.

Clamp b_resid to b_bcount in case the info field is larger. Fix a KASSERT
in physio() when a media error occurs on my SDLT320 drive (maybe this drive
is bogus for not setting the highter bits to 0 in the INFO field in this
case).

Fix a watchdog timeout and "block failed to stop" problem on BCM5701 B5 card.
2) Fix incorrect register write.

3) Wait more long time for PCISTATE register to return to its original

- Replace most inline assembly with proper functions. As a side effect
this reduces the size of amd64 GENERIC by about 120kB, and i386 by a
smaller amount. Nearly all of the inlines did something slow, or something
that does not need to be fast.
- Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL.
In that case make them inlines. Makes curlwp LKM and preemption safe.
- Make bus_space and bus_dma more LKM friendly.
- Share a few more files between the ports.
- Other minor changes.

- Fix a memleak: add sysmon_power_destroy_dictionary() and remove

- If the chip supports jumbo frames

that we can rewrite the physaddr field of the descriptor later, as it
might be partially overwritten by the hw

Those changes make my nfe(4) stable in both cases (defining NFE_NO_JUMBO

In nfe_start() do a fast return if IFF_OACTIVE is set, in
this case we need a Tx interrupt to clean up the DMA ring
before if_start can be properly called.
