Commit Message

Chen, Jing D Nov. 4, 2014, 10:01 a.m. UTC
From: "Chen Jing D(Mark)" <jing.d.chen@intel.com>

The change includes several parts:
1. Clear pool bitmap when trying to remove specific MAC.
2. Define RSS, DCB and VMDQ flags to combine rx_mq_mode.
3. Use 'struct' to replace 'union', which to expand the rx_adv_conf
   arguments to better support RSS, DCB and VMDQ.
4. Fix bug in rte_eth_dev_config_restore function, which will restore
   all MAC address to default pool.
5. Define additional 3 arguments for better VMDQ support.
