rt2x00: Fix beacon skew in rt2800pci 2012-03-12T18:21:49+00:00 Helmut Schaa helmut.schaa@googlemail.com 2012-03-09T14:31:50+00:00 290d60891eb659e52204ec209e08cc0cabc5b99f rt2800pci is suffering from beacon skew in AP mode. Some powersaving clients (like VOIP phones) are getting into trouble after some time when the beacon skew is getting too big. The ralink legacy drivers contain a function that indicates that the beacon timer is off by 1us per tbtt. And this function works around that by reducing the beacon interval for every 64th beacon transmission by 64us (the smallest possible value). Do the same in rt2800pci. This allows proper powersaving when rt2800pci is used in AP mode. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
