New Revision: 320055
URL: https://svnweb.freebsd.org/changeset/base/320055
Log:
- Fix incorrect values in the computation of CCK and OFDM transmit power
for the rtl8188eu chipset
- Rename struct r92c_rom member names: s/channel_plan/reserved5/,
s/xtal_calib/channel_plan to be compliant with definitions of the efuse
in vendor hal_pg.h
