Jijie Shao says:

====================
There are some bugfix for the HNS3 ethernet driver

ChangeLog:
v2 -> v3:
  - Rewrite the commit logs of net: hns3: add sync command to sync io-pgtable' to
    add more verbose explanation, suggested Paolo.
  - Add fixes tag for hardware issue, suggested Paolo and Simon Horman.
v2: https://lore.kernel.org/all/20241018101059.1718375-1-shaojijie@huawei.com/
v1 -> v2:
  - Pass IRQF_NO_AUTOEN to request_irq(), suggested by Jakub.
  - Rewrite the commit logs of 'net: hns3: default enable tx bounce buffer when smmu enabled'
    and 'net: hns3: add sync command to sync io-pgtable'.
v1: https://lore.kernel.org/all/20241011094521.3008298-1-shaojijie@huawei.com/
