This causes hangs, and IP will see lots of garbage packets. There is even the potential for data corruption if a later arriving packet DMA's into freed memory. It looks like a hardware bug because status arrives for a packet but no data is there. Until this bug is worked out, block the user from bringing up both ports at once.
