The new RV2P firmware fixes 2 issues:

1. The jumbo rx buffer page size is now configurable and set to the
   proper PAGE_SIZE.  Before, it was assumed to be always 4K.

2. Driver sometimes would crash when receiving jumbo packets mixed
   with firmware management packets.  This was caused by the old
   firmware DMA'ing to the wrong address.
