svn commit: r302446 - head/sys/dev/ath/ath_hal

[Adrian Chadd]

Author: adrian
Date: Fri Jul  8 19:16:50 2016
New Revision: 302446
URL: https://svnweb.freebsd.org/changeset/base/302446

Log:
  [ath_hal] extend the TX/RX descriptor layout to include location/beamforming fields.
  
  * extend the TX timestamp to 32 bits, as the AR5416 and later does a full
    32 bit TX timestamp instead of 15 or 16 bits.
  * add RX descriptor fields for PHY uploaded information (coming soon)
  * add flags for RX/TX fast timestamp, hardware upload, etc
  * add a flag for TX to request ToD/ToA location information.
