Merge branch 'net-hns3-misc-updates-for-next'
Huazhong Tan says: ==================== net: hns3: misc updates for -next This series includes some misc updates for the HNS3 ethernet driver. #1 adds support for 1280 queues #2 adds mapping for BAR45 which is needed by RoCE client. #3 extend the interrupt resources. #4&#5 add support to query firmware's calculated shaping parameters. ==================== Link: https://lore.kernel.org/r/1605863783-36995-1-git-send-email-tanhuazhong@huawei.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
