Author: adrian Date: Thu Jul 4 19:45:34 2013 New Revision: 252717 URL: http://svnweb.freebsd.org/changeset/base/252717 Log: Enable the station-side power management flag. It's not enabled by default in net80211 so this is a no-op unless if you enable it (ifconfig wlan0 powersave). Tested: * iwn0: <Intel WiFi Link 5100> mem 0xf4300000-0xf4301fff irq 17 at device 0.0 on pci3 TODO: * .. test on all the other NICs * See if I have to disable it during scan and such * Make it configurable live, rather than only after it's done its initial receive calibration.
