Comment 28 for bug 965043

After testing out the various commits in drivers/net/wireless/rt2x00 , I can tell you it is this one causing the problem:

    mac80211: pass vif param to conf_tx() callback

    tx params should be configured per interface.
    add ieee80211_vif param to the conf_tx callback,
    and change all the drivers that use this callback.

    The following spatch was used:
    @rule1@
    struct ieee80211_ops ops;
    identifier conf_tx_op;
    @@
        ops.conf_tx = conf_tx_op;

    @rule2@
    identifier rule1.conf_tx_op;
    identifier hw, queue, params;
    @@
        conf_tx_op (
    - struct ieee80211_hw *hw,
    + struct ieee80211_hw *hw, struct ieee80211_vif *vif,
                u16 queue,
                const struct ieee80211_tx_queue_params *params) {...}
