    "content": "From: \"Chen Jing D(Mark)\" <jing.d.chen@intel.com>\n\nThe change includes several parts:\n1. Clear pool bitmap when trying to remove specific MAC.\n2. Define RSS, DCB and VMDQ flags to combine rx_mq_mode.\n3. Use 'struct' to replace 'union', which to expand the rx_adv_conf\n   arguments to better support RSS, DCB and VMDQ.\n4. Fix bug in rte_eth_dev_config_restore function, which will restore\n   all MAC address to default pool.\n5. Define additional 3 arguments for better VMDQ support.\n\nSigned-off-by: Chen Jing D(Mark) <jing.d.chen@intel.com>\nAcked-by: Konstantin Ananyev <konstantin.ananyev@intel.com>\nAcked-by: Jingjing Wu <jingjing.wu@intel.com>\nAcked-by: Jijiang Liu <jijiang.liu@intel.com>\nAcked-by: Huawei Xie <huawei.xie@intel.com>\n---\n lib/librte_ether/rte_ethdev.c |   12 +++++++-----\n lib/librte_ether/rte_ethdev.h |   39 ++++++++++++++++++++++++++++-----------\n 2 files changed, 35 insertions(+), 16 deletions(-)",
