- Change the Tx:Rx on-chip RAM allocation ratio based on MTU:
=> 82547: > 8192 18K:22K, else 10K:30K
=> others: > 8192 24K:40K, else 16K:48K
Values derived from Linux driver.
- On the 82547, keep track of how much of the Tx FIFO has been used.
When in half-duplex mode, don't let packets wrap around the FIFO ring
buffer, because that causes the chip to croak. Detect this, stall the
Tx queue, use a timer to wait for the packets to drain from the Tx FIFO,
reset the internal FIFO pointers, and restart the Tx queue. Basic
algorithm (and some magic numbers) derived from FreeBSD and Linux drivers.
methods use va_list in a manner that is directly related to the public API.
This makes it much easier to write dynamic nsswitch backends for getpwent(3).
Per my proposal on tech-userlevel.
Implement getpwgid_r() and getpwnam_r() APIs per the POSIX 1003.1, 2004 Ed.
These aren't fully reentrant or threadsafe yet, because the compat stuff
currently uses non-reentrant data sources (getnetgrent(3), getpwent(3)),
and there is probably some locking to be improved in the backends.
This will be fixed in the near future.
We also need to add _SC_GETPW_R_SIZE_MAX to sysconf(3).
Fix the compat `+' prototype override so getpwnam(3) and getpwuid(3) DTRT.
Improve the description of pw_class and pw_gecos.
a given address family and a peer only supports the family localhost does
not support. For example: configure a kernel without IPV6, and then
add a line in ntp.conf server <ipv6addr>. We report that the server is
unreachable and we keep going because there might be more servers around?
XXX: What if it is the last server? Should we detect this? It is not nice
to just bail on this error, because a server might lose its ipv4 address
and only advertise ipv6.
if ni == NULL and the operating mode was not "ad hoc" or "ad hoc
demo." That crashed the kernel. Now, if the operating mode is
not "ad hoc (demo)," and ni == NULL, return NULL right away.
Also, if ieee80211_dup_bss returns NULL, return NULL right away.
This doesn't fix a bug, but it makes clear how this works.

bitrange for nsdispatch(3) return values.
* Tweak documentation comments in nsswitch.h
* Ensure the result from the back-end method is masked with
NS_STATUSMASK before nsdispatch(3) returns it.
sense, since 1) the condition is quite normal condition and 2) there is
pool between us and uvm.
- Make the step of allocation possibility a bit seamless by moving the origin
of curve from 0 to lowater mark.
Simon told that this helps for interactive performance when there is heavy
disk activity in PR#27057.
disklabels nested inside an MBR "NetBSD" or "386BSD" partition (first
one found is considered authoritative for the disk), or in one of several
known locations for various NetBSD platforms. It can read native or other-
endian disklabels (code is there, but not tested).
If you want to play with this, exercise caution; you can't currently
mountroot on a wedge (setroot() needs some work). Enabled by the
DKWEDGE_METHOD_BSDLABEL kernel option.
all keymaps except the US english one can be removed from the kernel
with this option, which results in a space gain of about 10kB.
XXX it would be nice if we could strip down more kernel facilities
