Hi Gavin,
     Thanks for your comments, I will fix the code style issue in Patch v5, and the bit operation for
hinic_test_bit and others has beed replaced with common rte_io_XX_bit APIs by Joyce Kong's pathces, I will check
other remained bit operations and replace it with the common one.

Best Regards
Xiaoyun Wang
