The code can be divided into two major parts. Gdma_main.c is the one to bring up the hardware board and drives all underlying hardware queue infrastructure. Mana_en.c contains all main ethernet driver code.

The hardware will be publicly available in Azure only. But I don't know when. The code has been tested internally.
