From: Gertjan van Wingerde Date: Sat, 8 May 2010 21:40:26 +0000 (+0200) Subject: rt2x00: Fix beaconing on rt2800. X-Git-Tag: v2.6.35-rc1~473^2~167^2~3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3b9f0ed78cf2eb678edd60d74a4a36f5947d003d;p=platform%2Fkernel%2Flinux-3.10.git rt2x00: Fix beaconing on rt2800. According to the Ralink vendor driver for rt2800 we don't need a full TXD for a beacon but just a TXWI in front of the actual beacon. Fix the rt2800pci and rt2800usb beaconing code accordingly.
