Ethminer Adoption

Ethminer is one of the most popular open-source mining software. We provide a patch to modify ethminer to adopt Xilinx solution. Basically we modify the opencl branch in ethminer. When Epoch nubmer change, it will stop mining and run dag_gen_kernel to generate latest DAG dataset and do necessary remapping for ethash_kernel. When resume mining, it will keep communicate with mining pool and get latest work. Based on the latest work, it will setup cofig for ethash_kernel and run. After ethash_kernel finished, it will check the returned result and commit successful nonce to mining pool.
