Comment 3 for bug 203758

That bug is caused because register_qdisc() fails in mac80211.
And that seems to only be possible when the same Qdisc_ops is registered twice.

In the package I see you create a rt2x_mac80211 module, but that is not needed when you use the linux-wireless package you can simply use that mac80211 for all drivers (along with the other drivers provided in that package). Using 2 mac80211 versions will only lead to "bad things".
