- Lessen the contiguity requirement for the journal so that it is more
likely to succeed.
- Print device details only when verbose boot is enabled.
- Add debug output for shared memory access.
- Add debug statistics (checksum offload & VLAN frame counters).
- Modify TX path to update consumer index for each frame completed
rather than updating the consumer index only once for a group of
frames to improve small packet performance.
- Print driver/firmware pulse messages only when verbose boot
is enabled.
- Add debug sysctl to clear statistics.
- Fix more style(9) violations.

architecture from page queue lock to a hashed array of page locks
(based on a patch by Jeff Roberson), I've implemented page lock
support in the MI code and have only moved vm_page's hold_count
out from under page queue mutex to page lock. This changes
pmap_extract_and_hold on all pmaps.

controller, I'm not sure whether this is also applicable to SiS190
so this feature is only activated on SiS191 controller.
In theory, controller reinitialization is not needed when VLAN tag
configuration is changed, but xclin said controller was not stable
whenever toggling VLAN tag bit. To address that, sge(4)
reinitialize controller for VLAN configuration which seems to work
as expected. VLAN tag information for TX/RX descriptor and
configure bit of RxMacControl register was found by xclin.

register. Due to lack of SiS190 controller, I'm not sure whether
this is also applicable to SiS190 so this feature is only activated
on SiS191 controller.
The controller can pad 10 bytes before DMAing a received frame to
RX buffer and received bytes include the padded bytes. This padding
is very useful on strict-alignment architectures because driver
does not have to copy received frame to align IP header on 4 bytes
boundary. It also gives better RX performance on non-strict
alignment architectures. Special thanks to xclin to give me
valuable register information. Without his enthusiastic trial and
errors this wouldn't be even possible.
While I'm here tighten validity check of received frame. Controller
clears RDS_CRCOK bit when it received bad CRC frames. xclin found
that using loop back testing.

is one of key registers to get various offloading features as well
as performance. Blindly clearing unrelated bits can result in
unexpected results.

than checking each page for PG_UNMANAGED, check the vm object's type.
Only OBJT_PHYS can have unmanaged pages. Eliminate a pointless counter.
The vm object is locked, that lock is never released by the inner loop,
and the set of pages contained by the vm object is not changed by the
inner loop. Therefore, the counter serves no purpose.
Clearing a page table entry's accessed bit and setting the page's
PG_REFERENCED flag in pmap_protect() can't really be justified, so
don't do it. Moreover, on ia64, don't set the page's dirty field
unless pmap_protect() is removing write access.

"Whitspace" churn after the VIMAGE/VNET whirls.
Remove the need for some "init" functions within the network
stack, like pim6_init(), icmp_init() or significantly shorten
others like ip6_init() and nd6_init(), using static initialization
again where possible and formerly missed.
Move (most) variables back to the place they used to be before the
container structs and VIMAGE_GLOABLS (before r185088) and try to
reduce the diff to stable/7 and earlier as good as possible,
to help out-of-tree consumers to update from 6.x or 7.x to 8 or 9.
This also removes some header file pollution for putatively
static global variables.
Revert VIMAGE specific changes in ipfilter::ip_auth.c, that are
no longer needed.

This is done in kern_ntptime, perhaps not the best place.
This is done using resettodr().
Some features:
- make save period configurable via tunable and sysctl
- period of zero disables saving, setting a non-zero period re-enables
it or reschedules it
- do saving only if system clock is ntp-synchronized
- save on shutdown

emulated by BIOS using SMI interrupt. On those chipsets reading
from the status port may be thousand times slower than usually.
Sometimes this emilation is not working properly resulting in
commands timing out and since we assume that inb() operation
takes very little time to complete we need to adjust number of
retries to keep waiting time within a designed limits (100ms).
Measure time it takes to make read_status() call and adjust
number of retries accordingly.
To keep it simple, use TSC to measure inb() performance and
keep it to amd64-only, since TSC may not available on older
CPUs.
Also enable detection of the AT controller absence on amd64.

named_chrootdir IS set, named-checkconf fails because it
cannot find the conf file. Fix this by making checkconf a
variable that includes "-t $named_chrootdir" as needed.
Notice of the bug and suggested direction for the fix from [1].
Using required_files for named.conf is overkill ever since
I added the named-checkconf call, so rather than update the
logic to handle the case described above, remove it. This
also handles the case where named_chroot_autoupdate IS set
but the symlink doesn't exist yet.
