V3 - fix a typo error in #1 reported by Jakub Kicinski. rewrite #9 commit log. remove #11 from this series. V2 - reorder #2 & #3 to fix compiler error. fix some checkpatch warnings in #10 & #11. previous version: V3: https://patchwork.ozlabs.org/project/netdev/cover/1605151998-12633-1-git-send-email-tanhuazhong@huawei.com/ V2: https://patchwork.ozlabs.org/project/netdev/cover/1604892159-19990-1-git-send-email-tanhuazhong@huawei.com/ V1: https://patchwork.ozlabs.org/project/netdev/cover/1604730681-32559-1-git-send-email-tanhuazhong@huawei.com/ Huazhong Tan (4): net: hns3: add support for configuring interrupt quantity limiting net: hns3: add support for querying maximum value of GL net: hns3: add support for 1us unit GL configuration net: hns3: rename gl_adapt_enable in struct hns3_enet_coalesce drivers/net/ethernet/hisilicon/hns3/hnae3.h | 1 + drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c | 1 + drivers/net/ethernet/hisilicon/hns3/hns3_enet.c | 99 ++++++++++++++++------ drivers/net/ethernet/hisilicon/hns3/hns3_enet.h | 17 +++- drivers/net/ethernet/hisilicon/hns3/hns3_ethtool.c | 71 +++++++++++++--- .../net/ethernet/hisilicon/hns3/hns3pf/hclge_cmd.h | 8 ++ .../ethernet/hisilicon/hns3/hns3pf/hclge_main.c | 7 ++ .../ethernet/hisilicon/hns3/hns3vf/hclgevf_cmd.h | 8 ++ .../ethernet/hisilicon/hns3/hns3vf/hclgevf_main.c | 7 ++ 9 files changed, 182 insertions(+), 37 deletions(-) Reviewed-by: Jesse Brandeburg
