yeah that's an important one, SECOND_REQ can be ignored entirely.

req gets set to "1" when the l_in.valid signal is raised, and the state set
to ACK_WAIT.



btw do not be fooled by the FSM being in a combinatorial block, look at the
start rising_edge, the "v" is copied to r_in as a synchronous thing.

therefore everything that goes into "v" will become "r" on the next cycle.
