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.
