Previous send v2 had a null pointer error in it.
When rt2500usb and rt73usb will start using beacontemplates,
they would also need a control structure to be passed along to
correctly set the tx parameters.
This patch will add a ieee80211_tx_control pointer to the
ieee80211_if_init_conf structure. This pointer is only a reference
to a local variable so drivers will not need to call kfree() on it.
