122 * The Queue Heads and Transfer Descriptors and accessed

124 * concurrently. This means that they have to be accessed

127 * be accessed by it and anything goes. As soon as a
128 * TD is accessible by the controller it "owns" the td_status
129 * field; it will not be written by the CPU. Similarly
130 * the controller "owns" the qh_elink field.
