Hello.

Without this change, musb will not correctly send out a ZLP if the
last transfer is the maxpacket size and request->zero is set.

   I would also look at the host side about ZLP -- I had an impression that
with Mentor DMA ZLP just can't be sent...

I'm not very familiar with the host side code. Do you know why we cannot send a ZLP?

   I should have said that it doesn't ever send final ZLP.

What would happen if we simply set TxPktRdy without loading the FIFO?

   It should send a ZLP. But the code doesn't seem to do it.
