processors unless the invariant TSC bit of CPUID is set. Intel processors
may stop incrementing TSC when DPSLP# pin is asserted, according to Intel
processor manuals, i. e., TSC timecounter is useless if the processor can
enter deep sleep state (C3/C4). This problem was accidentally uncovered by
r222869, which increased timecounter quality of P-state invariant TSC, e.g.,
for Core2 Duo T5870 (Family 6, Model f) and Atom N270 (Family 6, Model 1c).

resource allocation from an x86 Host-PCI bridge driver so that it can be
reused by the ACPI Host-PCI bridge driver (and eventually the MPTable
Host-PCI bridge driver) instead of duplicating the same logic. Note that
this means that hw.acpi.host_mem_start is now replaced with the
hw.pci.host_mem_start tunable that was already used in the non-ACPI case.
This also removes hw.acpi.host_mem_start on ia64 where it was not
applicable (the implementation was very x86-specific).
While here, adjust the logic to apply the new start address on any
"wildcard" allocation even if that allocation comes from a subset of
the allowable address range.

register both status change and link state change callbacks.
Implement checking valid link in state change callback and poll
active link state in vr_tick(). This allows immediate detection of
lost link as well as protecting driver from frequent link flips during
link renegotiation. taskq implementation was removed because driver
now needs to poll link state in vr_tick().
While I'm here do not report current link state if interface is not
running.

o Consider No CIS a normal event and stop whining about it so much
(too many cards are like this, espeically usb/firewire cards).
o Add comments to the cis reading code.
o Made the read from config space a smidge easier to read and eliminate
a loop that can be done mathematically.
uid<->username mapping cache with an entry when another entry
for that uid is already loaded. This fixes a case where the
mapping of "toor" would replace "root" when the daemon was started,
resulting in no mapping for "root" until the cache entry for "toor"
timed out.
The algorithm is inefficient, but since it is only done once when
the daemon is started up, I don't think that's an issue.

present. Only call the bus to check if we actually do timeout so we
don't affect the normal case (since this case needn't be optimized and
this guards against all races).
- Remove unneeded linking against libmd. libulog depends on this
library, but the ulog-helper tool itself does not.
- Change the comment at the top to mention utmpx instead of utmp, wtmp
and lastlog.
- Simply use user_from_uid() to translate to a username string.
- Put variable declarations together.
gpart_write_partcode_vtoc8 does access out of range of allocated memory.

child is still present. If not, return 'handled' and don't print
anything (this is expected behavior). We expect an interrupt on eject,
power-down and/or shutdown.
particular flow control and dma coalesce. Also improve the
sysctl operation on those too.
Add IPv6 detection in the ioctl code, this was done for
ixgbe first, carrying that over.
Add resource ability to disable particular adapter.
Add HW TSO capability so vlans can make use of TSO
operations while traversing non-exported file systems. This is
required for some non-FreeBSD clients to do NFSv4 mounts. Found during
the recent NFSv4 interoperability Bakeathon.

Since the only parameter that we check is size of bootcode, then
allow only two sizes: size of boot1 and size of /boot/boot.
This partially protects users from losing ability to boot if incorrect
bootcode is specified.

TX for the given TID needs to be paused during ADDBA requests (and unpaused
once the session is established.) Since net80211 currently doesn't implement
software aggregation, if this pause/unpause is done in the driver (as it
is in my development branch) then it will need to be unpaused both on
ADDBA response and on ADDBA timeout.
This callback allows the driver to unpause TX for the relevant TID.
