So we reserve updating link status using timers in PF driver,\nand add querying link status by issuing command to the firmware in\n'.link_update' ops implementation function named hns3_dev_link_update to\nsolve the out of date link status.\n\nSigned-off-by: Hongbo Zheng <zhenghongbo3@huawei.com>\nSigned-off-by: Wei Hu (Xavier) <xavier.huwei@huawei.com>\nSigned-off-by: Huisong Li <lihuisong@huawei.com>\n---\nv1 -> v2:\n\t1.Add querying link status by issuing command to the firmware\n\t  in '.link_update' ops implementation function named\n\t  hns3_dev_link_update to solve the out of date link status.\n---\n drivers/net/hns3/hns3_ethdev.c | 14 +++++++++++--\n drivers/net/hns3/hns3_ethdev.h |  1 +\n drivers/net/hns3/hns3_mbx.c    | 37 ++++++++++++++++++++++++++++++++++\n drivers/net/hns3/hns3_mbx.h    |  8 ++++++++\n 4 files changed, 58 insertions(+), 2 deletions(-)",
