handling in order to reduce interrupt overhead which results in
better performance.
- Call ether_ifdetach(9) before stopping the controller and the
callouts detach in order to prevent active BPF listeners to clear
promiscuous mode which may lead to the tick callout being restarted
which will trigger a panic once it's actually gone.
- Add explicit IFF_DRV_RUNNING checking in order to prevent extra
link up/down events when using dhclient(8).
- Use the correct macro for deciding whether 2/3 of the available TX
descriptors are used.
- Wrap the RX fault printing in #ifdef CAS_DEBUG in order to not
unnecessarily frighten users and as debugging was the actual
intention. Real errors caused by these faults still will be
accumulated as input errors. It might be a good idea to later on
add driver specific counters for the faults though.

- r187144: Add a reference to the config(5) manpage and
to the "env" kernel config option.
- Add/enable the default USB drivers. Originally the USB
controller and keyboard drivers were disabled as these
interacted badly with the Open Firmware console driver,
i.e. caused the keyboard to not work with ofw_console(4).
Even when switch to uart(4) and the frame buffer drivers
most of the USB drivers still were kept disabled as
several of them, amongst others all of the drivers for
USB Ethernet controllers, weren't endian clean. With the
new USB stack these problem should be gone now so there's
no longer a reason to not include the same set of USB
drivers amd64 does.
o Remove the commented out device ofw_console; apart from it
being currently broken by some TTY changes one really needs
to know how to actually enable and make it work correctly.
them under COMPAT_FREEBSD[4567]. Starting with FreeBSD 5.0 the SYSV IPC
API was implemented via direct system calls (e.g. msgctl(), msgget(), etc.)
rather than indirecting through the var-args *sys() system calls. The
shmsys() system call was already effectively deprecated for all but
COMPAT_FREEBSD4 already as its implementation for the !COMPAT_FREEBSD4 case
was to simply invoke nosys().
The kernel does not log floppy media errors anymore.
In fdcontrol, do always open the file descriptor in read-only mode so
it can operate on read-only media, as there is no longer a separate
control device to operate on.
longer useful for the FD_STYPE and FD_SOPTS ioctls to insist on being
issued on a writable file descriptor. Otherwise, there's no longer a
chance to set the drive type or options when a read-only medium is
present in the drive, as there is no way to obtain a writable fd then.
call ether_ifdetach(9) before stopping the controller and the
callouts. The consensus is that the latter is now safe to do and
should also solve the problem of active BPF listeners clearing
promiscuous mode can result in the tick callout being restarted
which in turn will trigger a panic once it's actually gone.
side fails, the entry in the cache is left with no valid context
(gd_ctx == GSS_C_NO_CONTEXT). As such, subsequent hits on the cache
will result in persistent authentication failure, even after the user has
done a kinit or similar and acquired a new valid TGT. This patch adds a test
for that case upon a cache hit and calls rpc_gss_init() to make another
attempt at getting valid credentials. It also moves the setting of gc_proc
to before the import of the principal name to ensure that, if that case
fails, it will be detected as a failure after going to "out:".

will write a single line of information without *any* EOL sequence.
Translate all the non-unix EOL's to the standard newline, and make
sure the final line includes a terminating newline. Logic is also
added to translate all unprintable characters to '?', but that is
#if-ed out for now.

prevents vm_map_insert from trying to account the entries for swap

While there, change FALSE to VMFS_NO_SPACE.
