as redoing all the menus to have proper, or at least non-hallucinogenic,
keyboard accelerators.
This requires my recent update to libdialog to work properly and will
probably also exhibit some other "interesting" behavior while the last
few missing screen clears are found (which is why I'm not going to MFC
immediately). At least now, however, sysinstall does not gratuitously
redraw random screens at the drop of a hat and drive serial console
installers out of their minds.
The variables "m_mclalloc_wid" and "m_mballoc_wid" were not in the
proper place. They should have been in uipc_mbuf.c and have been global,
not in mbuf.h and local per each file that uses mbuf.h.
Sorta bug fix:
In mbuf.h, the definitions of various things for KERNEL and not
KERNEL cases were very screwy. This fixes all of that which I could
find.
- Add a flag DC_TX_INTR_ALWAYS which causes the transmit code to
request a TX done interrupt for every packet. The PNIC seems to need
this to insure that the sent TX buffers get reaped in a timely fashion.
- Try to unreset the SIA as soon as possible after resetting the whole
chip.
- Change dcphy to support either 10/100 or 10Mbps only NICs. The
built-in 21143 ethernet in Compaq Presario machines is 10Mbps only
and it doesn't work right if we try to advertise 100Mbps modes during
autoneg. When restricted to only 10mbps modes, it works fine.
Note that for now, I detect this condition by checking the PCI
subsystem ID on this NIC (which has a Compaq vendor/device ID).
Yes, I know that's what the SROM is supposed to be for. I'm deliberately
ignoring the SROM wherever possible. Sue me.
The latter two fixes allow if_dc to work correctly with the built-in
ethernet on certain Compaq Presario boxes. There are liable to be quite
a few people using these as their home systems who might want to try
FreeBSD; may as well be nice to them.
Now if anybody out there has an Alpha miata with 10Mbps ethernet and
can show me the output from pciconf -l on their system, I'd be grateful.

you have problems with the old stuff.
o Enshrine the night of bared axes against wd. Strongly push
users to move to ata driver.
o Alpha users need to recompile klds after 11/29.
o Mention the sound driver bridge code commit of 11/22.
o change examples in 1205 entry from wd to ad.
o Talk about new dc driver replacing all of the drivers that
Bill Paul has ever written.[*]
Corrections to these entries welcome.

disk transaction overhead by reading larger blocks. This results in
better pipelining of requests/responses over the network and an almost
100% increase in cpu efficiency on the server. On a 100BaseTX network
NFS read performance increases from 8.5 MBytes/sec to 10 MB/sec (maxed
out), and cpu efficiency increases from 72% idle to 80% idle on the server.

This is the second part of the commit (the third -- link in usr.sbin/Makefile)
will be done after a more complete review by phk & obrien.
NOTE: the number of drivers included in the default configuration is very
minimal, mainly local clocks and the one I use RAWDCF. Anyone wanting to
have a more complete version will find recompilation very easy.

Change the info from ad_version, so the ATA version from the disk can

Call ata_dmainit with all dmamodes off when falling back to PIO mode,

- Check that space is still valid after obtaining the pipe lock.
- Defer the calculation of transfer size until the pipe
lock has been obtained.
- Update the pipe buffer pointers while holding the pipe lock.
2. Writes of size <= PIPE_BUF not always atomic.
- Allow an internal write to span two contiguous segments,
so writes of size <= PIPE_BUF can be kept atomic
when wrapping around from the end to the start of the
pipe buffer.
