I've brought the hal source code back to RELENG_7 but not connected it to the build and/or driver. I want folks to test this before I commit those changes. To do this you must have an up to date RELENG_7 code base and then apply this patch:

http://people.freebsd.org/~sam/ath_hal-releng7.patch

Then rebuild your kernel. There should be no changes to user apps. Beware however that custom kernel configurations will need to change; instead of:

device ath
device ath_hal
device ath_rate_sample

(or similar) you need:

device ath
device ath_hal
options AH_SUPPORT_AR5416
device ath_rate_sample

If you want to configure a subset of the chip support implied by ath_hal then you may not need the options line.

If you are using modules note that ath_hal and ath_rate_* modules no longer exist; they are now rolled into the ath module. If you use a rate control algorithm other than sample then you'll need to modify the ath module build or override by specifying ATH_RATE; e.g.

cd sys/modules/ath
make ATH_RATE=onoe

The updated hal code adds support for several parts but otherwise makes no effort to address driver bugs. You should see no regressions relative to operation w/ the older hal.

If you are running the 7.1 release you will need to import the hal code that is now in

sys/dev/ath/ath_hal

before following the above instructions. I have no idea if this will work for an earlier version of FreeBSD; if you're not running at least 7.1 my advise is to upgrade.

Please report any issues to this mailing list.
