[FE] State machines in 4.11

[Pat Thaler <pat_thaler@xxxxxxxxxxx>]

The state machines added in 4.11 don't appear to add any significant content. Also, the transmit one is broken. The way we have used state machines in the past, a UCT immediately transitions out of the state. It doesn't wait for actions initiated in the state to complete. Therefore, the transmit state machine presented will accept a new MA_DATA.request as soon as it gets it rather than waiting until the current transmit is done.

If the state machines are retained, the exit from GENERATE_TRANSMIT_FRAME should be conditioned on finishing the transmit.
