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: v3 -> v4: - Delete INITED_STATE in priv, suggested by Andrew. - Delete unnecessary defensive code in hbg_phy_start() and hbg_phy_stop(), suggested by Andrew. v3: https://lore.kernel.org/all/20240822093334.1687011-1-shaojijie@huawei.com/ 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/20240820140154.137876-1-shaojijie@huawei.com/ v1 -> v2: - fix build errors reported by kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202408192219.zrGff7n1-lkp@intel.com/ Closes: https://lore.kernel.org/oe-kbuild-all/202408200026.q20EuSHC-lkp@intel.com/ v1: https://lore.kernel.org/all/20240819071229.2489506-1-shaojijie@huawei.com/ 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/20240813135640.1694993-1-shaojijie@huawei.com/ 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.
