If you had one of the newer cores, then you needed newer firmware to get the 
correct file, but the older ones worked. However, I should never trust my 
memory. The TX and RX headers changed with firmware version 598.314. The change 
in the driver was introduced with commit 17030f4 in such a way that the older 
firmware versions still worked.

Ah, I know it by a different number.
