According to the Application Notes of the DM9000, only the 2 bits 0:1 of the status byte need to be checked to identify a valid packet in the fifo
But, The several different Application Notes do not all speak the same language on these bits. They do not disagree, but only 1 Application Note noted explicitly that only these 2 bits need to be checked. Even the datasheets do not mention anything about these 2 bits.
Because the old code, and the kernel check the whole byte, I left this piece untouched.
However, I tested all board/DM9000[A|E|EP] devices with this 2 bit check, so it should work.
Notice, that the 2nd iteration through this receive loop (when a 2nd packet is in the fifo) is much shorter now, compared to the older U-boot driver code, so that we can maybe run into a hardware condition now that was never seen before, or maybe was seen very unfrequently.

I can't get this to apply. Please re-base after applying your 6-patch set and the one that changes the order of rx status processing (or against the current net tree would be even better).
