From 5c3b685c79f38ac6b909b3650f3dad3993614cfb Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Thu, 3 Jun 2010 10:51:41 +0200 Subject: rt2x00: Push beacon TX descriptor writing to drivers. Not all the devices require a TX descriptor to be written (i.e. rt2800 device don't require them). Push down the creation of the TX descriptor to the device drivers so that they can decide for themselves whether a TX descriptor is to be created.
