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: v1 -> 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. v1: https://lore.kernel.org/all/20240731094245.1967834-1-shaojijie@huawei.com/ --- Jijie Shao (11): net: hibmcge: Add pci table supported in this module net: hibmcge: Add read/write registers supported through the bar space net: hibmcge: Add mdio and hardware configuration supported in this module net: hibmcge: Add interrupt supported in this module net: hibmcge: Implement some .ndo functions net: hibmcge: Implement .ndo_start_xmit function net: hibmcge: Implement rx_poll function to receive packets net: hibmcge: Implement some ethtool_ops functions net: hibmcge: Add a Makefile and update Kconfig for hibmcge net: hibmcge: Add maintainer for hibmcge net: add is_valid_ether_addr check in dev_set_mac_address MAINTAINERS | 7 + drivers/net/ethernet/hisilicon/Kconfig | 16 +- drivers/net/ethernet/hisilicon/Makefile | 1 + .../net/ethernet/hisilicon/hibmcge/Makefile | 10 + .../ethernet/hisilicon/hibmcge/hbg_common.h | 142 ++++++ .../ethernet/hisilicon/hibmcge/hbg_ethtool.c | 17 + .../ethernet/hisilicon/hibmcge/hbg_ethtool.h | 11 + .../net/ethernet/hisilicon/hibmcge/hbg_hw.c | 299 +++++++++++++ .../net/ethernet/hisilicon/hibmcge/hbg_hw.h | 48 ++ .../net/ethernet/hisilicon/hibmcge/hbg_irq.c | 180 ++++++++ .../net/ethernet/hisilicon/hibmcge/hbg_irq.h | 13 + .../net/ethernet/hisilicon/hibmcge/hbg_main.c | 245 +++++++++++ .../net/ethernet/hisilicon/hibmcge/hbg_mdio.c | 253 +++++++++++ .../net/ethernet/hisilicon/hibmcge/hbg_mdio.h | 13 + .../net/ethernet/hisilicon/hibmcge/hbg_reg.h | 109 +++++ .../hisilicon/hibmcge/hbg_reg_union.h | 266 +++++++++++ .../net/ethernet/hisilicon/hibmcge/hbg_txrx.c | 414 ++++++++++++++++++ .../net/ethernet/hisilicon/hibmcge/hbg_txrx.h | 37 ++ net/core/dev.c | 2 + 19 files changed, 2082 insertions(+), 1 deletion(-) create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/Makefile create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_common.h create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_ethtool.c create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_ethtool.h create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_hw.c create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_hw.h create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_irq.c create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_irq.h create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_main.c create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_mdio.c create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_mdio.h create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_reg.h create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_reg_union.h create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_txrx.c create mode 100644 drivers/net/ethernet/hisilicon/hibmcge/hbg_txrx.h
