-TODO:
-	- Rx block size is limited to < 2048, hardware bug?
-	- Group size is limited to < page size, kernel alloc/mmap API issues
-	- test whether Tx is transmitting data from provided buffers
-	- handle device unplug case
-	- handle temperature above threshold
-	- use bus address instead of physical address for DMA
-	- support for snapshot mode
-	- audit userspace interfaces
-	- get reserved major/minor if needed
