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.
