9ed9f02b67 Modify ath_descdma_cleanup() to handle ath_descdma instances with no
buffers.

ath_descdma is now being used for things other than the classical
combination of ath_buf + ath_desc allocations.  In this particular case,
don't try to free and blank out the ath_buf list if it's not passed in.

b39722d6dd Migrate the descriptor allocation function to not care about the number
of buffers, only the number of descriptors.

This involves:

* Change the allocation function to not use nbuf at all;
* When calling it, pass in "nbuf * ndesc" to correctly update how many
  descriptors are being allocated.

Whilst here, fix the descriptor allocation code to correctly allocate
a larger buffer size if the Merlin 4KB WAR is required.  It overallocates
descriptors when allocating a block that doesn't ever have a 4KB boundary
being crossed, but that can be fixed at a later stage.

0ff8c4269b Document the dataflash/mmc-sd issue. Add umass driver and usb. Boot
off da0s1a instead of ate0.  Note that MMC/SD is slot B.  Until I
switch over to NAND boot, dataflash booting will preclude having SD
cards inserted at boot, so this last bit is untested.

The TX EDMA completion path is going to need descriptors allocated but

f196ce3869 Add support for VALE bridges to the netmap core, see
http://info.iet.unipi.it/~luigi/vale/

VALE lets you dynamically instantiate multiple software bridges
that talk the netmap API (and are *extremely* fast), so you can test
netmap applications without the need for high end hardware.

This is particularly useful as I am completing a netmap-aware
version of ipfw, and VALE provides an excellent testing platform.

Also, I also have netmap backends for qemu mostly ready for commit
to the port, and this too will let you interconnect virtual machines
at high speed without fiddling with bridges, tap or other slow solutions.

The API for applications is unchanged, so you can use the code
in tools/tools/netmap (which i will update soon) on the VALE ports.

This commit also syncs the code with the one in my internal repository,
so you will see some conditional code for other platforms.
The code should run mostly unmodified on stable/9 so people interested
in trying it can just copy sys/dev/netmap/ and sys/net/netmap*.h
from HEAD

VALE is joint work with my colleague Giuseppe Lettieri, and
is partly supported by the EU Projects CHANGE and OPENLAB

0ba4723b9e The baud rate on CP1201/2/3 devices can be set in one of two ways:
- The USLCOM_SET_BAUD_DIV command (0x01)
 - The USLCOM_SET_BAUD_RATE command (0x13)

Devices based on the CP1204 will only accept the latter command, and ignore
the former.  As the latter command works on all chips that this driver
supports, switch to always using it.

A slight confusion here is that the previously used command was incorrectly
named USLCOM_BAUD_RATE - even though we no longer use it, rename it to
USLCOM_SET_BAUD_DIV to closer match the name used in the datasheet.

This change reflects a similar change made in the Linux driver, which was
submitted by preston.fick at silabs.com, and has been tested on all of the
uslcom(4) devices I have to hand.

8253dcabe7 Fix a problem when CARP is enabled on the interface for IPv4
but not for IPv6.  The current checks in nd6_nbr.c along with the
old version will result in ifa being NULL and subsequently the
packet will be dropped.  This prevented NS/NA, from working and
with that IPv6.

Now return the ifa from the carp lookup function in two cases:
1) if the address matches, is a carp address, and we are MASTER
   (as before),
2) if the address matches but it is not a carp address at all (new).

3f6e7b9b11 Add rmb() to tsc_read_##x to enforce serialization of rdtsc captures.
Intel Architecture Manual specifies that rdtsc instruction is not serialized,
so without this change, TSC synchronization test would periodically fail,
resulting in use of HPET timecounter instead of TSC-low.  This caused
severe performance degradation (40-50%) when running high IO/s workloads due to
HPET MMIO reads and GEOM stat collection.

Tests on Xeon E5-2600 (Sandy Bridge) 8C systems were seeing TSC synchronization
fail approximately 20% of the time.

b225878c75 Quirk MS keyboard so that function keys work
The function keys on a Microsoft Natural Egronomic Keyboard 4000 have been
repurposed as "Help", "Undo", "Redo" etc., and a special "F Lock" key is
required to return them to their normal purpose.

This change enables the UQ_KBD_BOOTPROTO quirk for the MS Natural 4000
keyboard to get the keys working again.  More extensive changes to the USB
keyboard infrastructure would be needed to fully support the "F Lock" mode
and the extended keys on this keyboard.
