+# Purpose: Allow easy access to specific driver options.
+#
+# Edit the following line to change, add or delete options:
+options 8812au rtw_drv_log_level=0 rtw_led_ctrl=1 rtw_vht_enable=1 rtw_power_mgnt=1 rtw_beamform_cap=0 rtw_dfs_region_domain=0 rtw_switch_usb_mode=0
+#
+# After editing is complete, save this file (if using nano: Ctrl + x, y, Enter)
+# and reboot to activate the changes.
+#
+# Documentation:
+#
+# -----
+#
+# Log options ( rtw_drv_log_level )
+#
+# 0 = NONE (default)
+# 1 = ALWAYS
+# 2 = ERROR
+# 3 = WARNING
+# 4 = INFO
+# 5 = DEBUG
+# 6 = MAX
+#
+# Note: You can save a log file that only includes RTW log entries by running
+# the following in a terminal:
+#
+# sudo ./save-log.sh
+#
+# Note: The name of the log file will be ```rtw.log```.
+#
+# -----
+#
+# LED options ( rtw_led_ctrl )
+#
+# 0 = Always off
+# 1 = Normal blink (default)
+# 2 = Always on
+#
+# -----
+#
+# VHT options ( rtw_vht_enable )
+#
+#  0 = Disable
+#  1 = Enable (default)
+#  2 = Force auto enable (use only for 5 GHz AP mode)
+#
+# Notes:
+# - A non-default setting can degrade performance greatly in managed mode.
+# - Option 2 allows 80 MHz channel width for 5GHz AP mode, such as when
+#   you are using hostapd.
+#
+# -----
+#
+# Power options ( rtw_power_mgnt )
+#
+# 0 = Disable power saving
+# 1 = Power saving on, minPS (default)
+# 2 = Power saving on, maxPS (not recommended for AP mode)
+#
+# -----
+#
+# Beamforming options ( rtw_beamform_cap )
+#
+# 0 = Disable (default)
+# 1 = SU Beamformer
+# 2 = SU Beamformee
+# 3 = SU Beamformer and SU Beamformee
+# 10= SU Beamformee and MU Beamformee
+# 11= SU Beamformer and SU Beamformee and MU Beamformee
+#
+# Note: MU Beamformer is not supported.
+#
+# -----
+#
+# Country Code options ( rtw_country_code )
+#
+# Note: Allows the Country Code to be set in cases where it is unable to
+# be obtained from the operating system.
+#
+# Example for the US: rtw_country_code=US
+# Example for Panama: rtw_country_code=PA
+# Example for Norway: rtw_country_code=NO
+# Example for Kuwait: rtw_country_code=KW
+# Example for Taiwan: rtw_country_code=TW

+# -----
+#
+# DFS Options ( rtw_dfs_region_domain )
+#
+# 0 = NONE (default)
+# 1 = FCC
+# 2 = MKK
+# 3 = ETSI
+#
+# Notes:
+# - Activates DFS channels in AP mode.
+# - DFS FCC 80 MHz channels for hostapd: 52(58), 100(106), 116(122) and 132(138)
+# - For more information: https://en.wikipedia.org/wiki/List_of_WLAN_channels
+#
+# Note: An AP needs to listen on a DFS channel for a period of 60 seconds
+# before transmitting on the channel. If any radar pulses are detected,
+# the AP cannot use that channel and will have to try a different channel.
+#
+# -----
+#
+# Select P2P interface in concurrent mode ( rtw_sel_p2p_iface )
+#
+# 0 = Sets interface 0 to be p2p interface
+# 1 = Sets interface 1 to be p2p interface (default) 
+#
+# -----
+#
+# USB options: ( rtw_switch_usb_mode )
+#
+# 0 = No switch (default)
+# 1 = Switch from usb 2.0 to usb 3.0
