Author: adrian Date: Tue May 9 04:15:07 2017 New Revision: 318005 URL: https://svnweb.freebsd.org/changeset/base/318005 Log: [iwm] Add basic powermanagement support via ifconfig wlan0 powersave. * The DEVICE_POWER_FLAGS_CAM_MSK flag was removed in the upstream iwlwifi in Linux commit ceef91c89480dd18bb3ac51e91280a233d0ca41f. * Add sc_ps_disabled flag to struct iwm_softc, which corresponds to mvm->ps_disabled in struct iwl_mvm in Linux iwlwifi. * Adds a hw.iwm.power_scheme tunable which corresponds to the power_scheme module parameter in Linux iwlwifi. Set this to 1 for completely disabling power management, 2 (default) for balanced powermanagement, and 3 for lowerpower mode (which does dtim period skipping). * Imports the constants.h file from iwlwifi as if_iwm_constants.h. * This doesn't allow changing the powermanagement setting while connected, also one can only choose between enabled and disabled powersaving with ifconfig (so switching between balanced and low-power mode requires rebooting to change the tunable). * After any changes to powermanagement (i.e. "ifconfig wlan0 powersave" to enable powermanagement, or "ifconfig wlan0 -powersave" for disabling powermanagement), one has to disconnect and reconnect to the accespoint for the change to take effect.
