[V3,net-next,00/11] Add support of HIBMCGE Ethernet Driver

Message

Jijie Shao Aug. 22, 2024, 9:33 a.m. UTC

This patch set adds the support of Hisilicon BMC Gigabit Ethernet Driver.

This patch set includes basic Rx/Tx functionality. It also includes
the registration and interrupt codes.

This work provides the initial support to the HIBMCGE and
would incrementally add features or enhancements.

ChangeLog:
v2 -> v3:
  - Add "select PHYLIB" in Kconfig, reported by Jakub.
  - Use ndo_validate_addr() instead of is_valid_ether_addr()
    in dev_set_mac_address(), suggested by Jakub and Andrew.
  v2: https://lore.kernel.org/all/[e-mail]/
v1 -> v2:
  - fix build errors reported by kernel test robot <[e-mail]>
    Closes: https://lore.kernel.org/oe-kbuild-all/[e-mail]/
    Closes: https://lore.kernel.org/oe-kbuild-all/[e-mail]/
  v1: https://lore.kernel.org/all/[e-mail]/
RFC v2 -> v1:
  - Use FIELD_PREP/FIELD_GET instead of union, suggested by Andrew.
  - Delete unnecessary defensive code, suggested by Andrew.
  - A few other minor changes.
  RFC v2: https://lore.kernel.org/all/[e-mail]/
RFC v1 -> RFC v2:
  - Replace linkmode_copy() with phy_remove_link_mode() to
    simplify the PHY configuration process, suggested by Andrew.
  - Delete hbg_get_link_status() from the scheduled task, suggested by Andrew.
  - Delete validation for mtu in hbg_net_change_mtu(), suggested by Andrew.
  - Delete validation for mac address in hbg_net_set_mac_address(),
    suggested by Andrew.
  - Use napi_complete_done() to simplify the process, suggested by Joe Damato.
  - Use ethtool_op_get_link(), phy_ethtool_get_link_ksettings(),
    and phy_ethtool_set_link_ksettings() to simplify the code, suggested by Andrew.
  - Add the null pointer check on the return value of pcim_iomap_table(),
    suggested by Jonathan.
  - Add the check on the return value of phy_connect_direct(),
    suggested by Jonathan.
  - Adjusted the layout to place the fields and register definitions
    in one place, suggested by Jonathan.
  - Replace request_irq with devm_request_irq, suggested by Jonathan.
  - Replace BIT_MASK() with BIT(), suggested by Jonathan.
  - Introduce irq_handle in struct hbg_irq_info in advance to reduce code changes,
    suggested by Jonathan.
  - Delete workqueue for this patch set, suggested by Jonathan.
  - Support to compile this driver on all arch in Kconfig,
    suggested by Andrew and Jonathan.
  - Add a patch to add is_valid_ether_addr check in dev_set_mac_address,
    suggested by Andrew.
  - Use macro instead of inline to fix the warning about compile-time constant
    in FIELD_PREP(), reported by Simon Horman.
  - A few other minor changes.
  RFC v1: https://lore.kernel.org/all/[e-mail]/
