just em, there is an igb driver (this follows behavior with our Linux drivers).
All adapters up to the 82575 are supported in em, and new client/desktop support
will continue to be in that adapter.
The igb driver is for new server NICs like the 82575 and its followons.
Advanced features for virtualization and performance will be in this driver.
Also, both drivers now have shared code that is up to the latest we have
released. Some stylistic changes as well.
Enjoy :)

Add "show sysregs" command to ddb. On i386, this gives gdt, idt, ldt,
cr0-4, etc. Support should be added for other platforms that have a
different set of registers for system use.
while still restricting auto-channel select to only those channels
permitted by regulatory constraints (sorta, we're still missing the
checks to honor radar and noadhoc status on channels). This somehow
got lost in the initial merge of the revised scanning code.

frames. This bug seems to happen on certain hardware model/revision
(e.g. 88E8053) but it's not identified which hardwares are affected.
Revision 1.4 of if_mskreg.h was not enough to workaround the bug.
To workaround it, inrease GMAC FIFO threshold by one FIFO word to
flush received pause frames.

only because there's a partition table where the boot sector has
boot code. Boot sectors without boot code look like a MBR for all
practical purposes. This change adds a check for the partition table
and fails the probe when it's obvously invalid. The assumption being
that the sector contains a boot sector and not a MBR.
More checks are needed to distinguish a boot secto without boot code
from a (empty) MBR.
This fixes the panic which happens when mdcreate_vnode() calls vn_close()
and mddestroy() calls it again further down the error handling path.

- Consolidate the code to humanize the size of a disk partition into a
single function based on the code for GPT partitions and use it for
GPT partitions, BSD slices, and BSD partitions.
- Teach the humanize code to use KB for small partitions (e.g. GPT boot
partitions now show up as 64KB rather than 0MB).
- Pad a few partition type names out so that things line up in the
common case.

global audit mutex and condition variables, with an sx lock which protects
the trail vnode and credential while in use, and is acquired by the system
call code when rotating the trail. Previously, a "message" would be sent
to the kernel audit worker, which did the rotation, but the new code is
simpler and (hopefully) less error-prone.

the limit in bytes) hard coded into both the kernel and userland.
Make both these limits a sysctl, so it is easy to change the limit.
If the userland part of ipfw finds that the sysctls don't exist,
it will just fall back to the traditional limits.
(100 packets is quite a small limit these days. If you want to test
TCP at 100Mbps, 100 packets can only accommodate a DBP of 12ms.)
Note these sysctls in the man page and warn against increasing them
without thinking first.

list of VPD pages it does support, and only query the serial number if
it's supported, else silently move on. This eliminates a lot of noise
during verbose booting, and will likely eliminate the need for most
NOSERIAL quirks.

the vnode interlock is not held. vn_printf() already correctly handles
locked and unlocked vnode interlocks, and all the in-tree vop_print
methods are interlock-agnostic.
Some code calls vprintf() with the vnode interlock held, that causes
unjustified panics with INVARIANTS (ffs_syncvnode() as example).

only anonymous default (OBJT_DEFAULT) and swap (OBJT_SWAP) objects should
ever have OBJ_ONEMAPPING set. However, vm_object_deallocate() was
setting it on device (OBJT_DEVICE) objects. As a result,
vm_object_page_remove() could be called on a device object and if that
occurred pmap_remove_all() would be called on the device object's pages.
However, a device object's pages are fictitious, and fictitious pages do
not have an initialized pv list (struct md_page).
To date, fictitious pages have been allocated from zeroed memory,
effectively hiding this problem. Now, however, the conversion of rotting
diagnostics to invariants in the amd64 and i386 pmaps has revealed the
problem. Specifically, assertion failures have occurred during the
initialization phase of the X server on some hardware.
