Author: adrian Date: Fri Jul 8 22:59:15 2016 New Revision: 302468 URL: https://svnweb.freebsd.org/changeset/base/302468 Log: [ath_hal] add in locationing timer support and capabilities. * add support to read the timer and capability * add support to enable/disable the location timer. On AR9380 at least, enabling the location timer is required to make the timer tick, otherwise location packets return a timestamp of 0. However, it then makes /all/ RX packets use the RX location timestamp instead of the TSF timestamp. So, unless I find another magical way to do location timestamping, we will have to dynamically switch things on/off and ensure the TX/RX path handles the "different" timestamps correctly.
