Series breakdown (5 patches): 01/05: net: ethernet/mucse: Add build support for rnpgbe - Kconfig/Makefile for MUCSE vendor, basic PCI probe (no netdev) 02/05: net: ethernet/mucse: Add N500/N210 chip support - netdev allocation, BAR mapping 03/05: net: ethernet/mucse: Add basic MBX ops for PF-FW communication - base read/write, write with poll ack, poll and read data 04/05: net: ethernet/mucse: Add FW commands (sync, reset, MAC query) - FW sync retry logic, MAC address retrieval, reset hw with base mbx ops in patch4 05/05: net: ethernet/mucse: Complete netdev registration - HW reset, MAC setup, netdev_ops registration Changelog: v11 -> v12: [patch 3/5]: 1. fix switch code style. 2. rename mbx struct define 'timeout_cnt to timeout_us', 'usec_delay to delay_us'. [patch 4/5]: 1. update function mucse_mbx_sync_fw. [patch 5/5]: 1. update commit for rnpgbe_xmit_frame. 2. update define position for 'struct mucse_hw_operations'. 3. remove struct dma. links: v11: https://lore.kernel.org/netdev/20250909120906.1781444-1-dong100@mucse.com/ v10: https://lore.kernel.org/netdev/20250903025430.864836-1-dong100@mucse.com/ v9 : https://lore.kernel.org/netdev/20250828025547.568563-1-dong100@mucse.com/ v8 : https://lore.kernel.org/netdev/20250827034509.501980-1-dong100@mucse.com/ v7 : https://lore.kernel.org/netdev/20250822023453.1910972-1-dong100@mucse.com v6 : https://lore.kernel.org/netdev/20250820092154.1643120-1-dong100@mucse.com/ v5 : https://lore.kernel.org/netdev/20250818112856.1446278-1-dong100@mucse.com/ v4 : https://lore.kernel.org/netdev/20250814073855.1060601-1-dong100@mucse.com/ v3 : https://lore.kernel.org/netdev/20250812093937.882045-1-dong100@mucse.com/ v2 : https://lore.kernel.org/netdev/20250721113238.18615-1-dong100@mucse.com/ v1 : https://lore.kernel.org/netdev/20250703014859.210110-1-dong100@mucse.com/ Dong Yibo (5): net: rnpgbe: Add build support for rnpgbe net: rnpgbe: Add n500/n210 chip support with BAR2 mapping net: rnpgbe: Add basic mbx ops support net: rnpgbe: Add basic mbx_fw support net: rnpgbe: Add register_netdev .../device_drivers/ethernet/index.rst | 1 + .../device_drivers/ethernet/mucse/rnpgbe.rst | 21 + MAINTAINERS | 8 + drivers/net/ethernet/Kconfig | 1 + drivers/net/ethernet/Makefile | 1 + drivers/net/ethernet/mucse/Kconfig | 34 ++ drivers/net/ethernet/mucse/Makefile | 7 + drivers/net/ethernet/mucse/rnpgbe/Makefile | 11 + drivers/net/ethernet/mucse/rnpgbe/rnpgbe.h | 75 ++++ .../net/ethernet/mucse/rnpgbe/rnpgbe_chip.c | 150 +++++++ drivers/net/ethernet/mucse/rnpgbe/rnpgbe_hw.h | 17 + .../net/ethernet/mucse/rnpgbe/rnpgbe_main.c | 311 +++++++++++++ .../net/ethernet/mucse/rnpgbe/rnpgbe_mbx.c | 421 ++++++++++++++++++ .../net/ethernet/mucse/rnpgbe/rnpgbe_mbx.h | 20 + .../net/ethernet/mucse/rnpgbe/rnpgbe_mbx_fw.c | 246 ++++++++++ .../net/ethernet/mucse/rnpgbe/rnpgbe_mbx_fw.h | 121 +++++ 16 files changed, 1445 insertions(+) create mode 100644 Documentation/networking/device_drivers/ethernet/mucse/rnpgbe.rst create mode 100644 drivers/net/ethernet/mucse/Kconfig create mode 100644 drivers/net/ethernet/mucse/Makefile create mode 100644 drivers/net/ethernet/mucse/rnpgbe/Makefile create mode 100644 drivers/net/ethernet/mucse/rnpgbe/rnpgbe.h create mode 100644 drivers/net/ethernet/mucse/rnpgbe/rnpgbe_chip.c create mode 100644 drivers/net/ethernet/mucse/rnpgbe/rnpgbe_hw.h create mode 100644 drivers/net/ethernet/mucse/rnpgbe/rnpgbe_main.c create mode 100644 drivers/net/ethernet/mucse/rnpgbe/rnpgbe_mbx.c create mode 100644 drivers/net/ethernet/mucse/rnpgbe/rnpgbe_mbx.h create mode 100644 drivers/net/ethernet/mucse/rnpgbe/rnpgbe_mbx_fw.c create mode 100644 drivers/net/ethernet/mucse/rnpgbe/rnpgbe_mbx_fw.h -- 2.25.1
