Wu, Jingjing Aug. 1, 2014, 7:08 a.m. UTC
support a new ethdev API rx_classification_filter_ctl for all 
the configuration or queries for receive classification filters.
this patch supports commands the API used below:
  RTE_CMD_FDIR_RULE_ADD
  RTE_CMD_FDIR_RULE_DEL
  RTE_CMD_FDIR_FLUSH
  RTE_CMD_FDIR_INFO_GET
