HEAD is now at 4a4cfe1 Bug fix for hygon vfio based mediated hct(Patch 1051) Fix Bug:    xumingkai.xmk@alibaba-inc.com    guangyi.wg@alibaba-inc.com Description:    An VM with multiple v-C-C-Ps will meet conflicts in index_value.    The conflict comes from incorrect buf memory values.    For instance, given the physical c-c-p vfio id list:          9 2 13 0 7 5 3 4 10 1 12 14 6 8 11    After c-c-p id(13)'s read(), followd ids (index_values) got incorrect value.    It's needed to clean the buf memory via memset for each read().
