Well, something in mac80211 was changed that breaks this. mac80211 currently seems to assume that the number of queues does not change after ieee80211_register, which was not the case previously. This breaks the QoS disable, because b43 modifies the nr of queues variable in the ieee80211_hw structure. > This patch adds a config option to allow disabling QoS from the beginning. > This is the only way to workaround the described problem when building the > b43 driver in-kernel, as in that case modparam_qos can't be changed. > > Signed-off-by: Albert Herranz <albert_herr...@yahoo.es> Why are we currently adding all kind of workaround patches instead of fixing the bugs? This bug's been there for months, so I don't see a reason to push out a workaround now. -- Greetings, Michael. _______________________________________________ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
