The data\nfrom hardware follows the multiplexing and aggregation protocol (MAP).\n\nThis driver can be used to register onto any physical network device in\nIP mode. Physical transports include USB, HSIC, PCIe and IP accelerator.\n\nrmnet driver helps to decode these packets and queue them to network\nstack (and encode and transmit it to the physical device).\n\nv1: Same as the RFC patch with some minor fixes for issues reported by\nkbuild test robot.\n\nv1->v2: Change datatypes and remove config IOCTL as mentioned by David.\nAlso fix checkpatch issues and remove some unused code.\n\nv2->v3: Move location to drivers/net and rename to rmnet. Change the\nuserspace - netlink communication from custom netlink to rtnl_link_ops.\nRefactor some code. Use a fixed config for ingress and egress.\n\nv3->v4: Move location to drivers/net/ethernet/qualcomm/.\nFix comments from Stephen and Jiri -\nSplit the ether and arp type changes into seperate patches.\nRemove debug and custom logging and switch to standard netdevice log.\nRemove module parameters. Refactor and change some code style issues.\n\nv4->v5: Rename some structs and variables. Move the initializer\nbefore the for loop start. Put the arp type in correct sequence.\n\nv5->v6: Fix comments from Dan -\nUse the upper link API. As a result, remove all the refcounting logic.\nDevice refcount is explicitly held on real_dev on rx_handler\nregistration only. Modifiy the flow control struct. Remove the unused\nethernet mode handling.\n\nv6->v7: Fix comments from David - Add newline to end of Makefile. Remove\ninline from .c files. Move the module init/exit to rmnet config. Fix an\nerror reported by kbuild test robot for an unused file.\n\nv7->v8: Use a smaller value for ETH_P_MAP as mentioned by David. Change\nnetdev_info to netdev_dbg as mentioned by Andew. Fix comments from\nStephen regarding netdev_priv and sparse related errors of using 0 as NULL\n\nv8->v9: Fix comments from David - Remove the CFLAG rule. Change the way\nrmnet devices are freed. Instead of using a workqueue to unregister devices\nindividually, go through the list and free all devices within the rtnl_lock().\n\nv9->v10: Actually fix the locking as mentioned by David. The locking scheme is\nmentioned in a comment in rmnet_config.c. Change comment near MAP type\ndefinition as mentioned by Dan. Refactor some code.\n\nv10->v11: Allow RMNET to compile as a module as mentioned by David\n\nSubash Abhinov Kasiviswanathan (3):\n net: ether: Add support for multiplexing and aggregation type\n net: arp: Add support for raw IP device\n drivers: net: ethernet: qualcomm: rmnet: Initial implementation\n\n Documentation/networking/rmnet.txt | 82 ++++\n drivers/net/ethernet/qualcomm/Kconfig | 2 +\n drivers/net/ethernet/qualcomm/Makefile | 2 +\n drivers/net/ethernet/qualcomm/rmnet/Kconfig | 12 +\n drivers/net/ethernet/qualcomm/rmnet/Makefile | 10 +\n drivers/net/ethernet/qualcomm/rmnet/rmnet_config.c | 419 +++++++++++++++++++++\n drivers/net/ethernet/qualcomm/rmnet/rmnet_config.h | 56 +++\n .../net/ethernet/qualcomm/rmnet/rmnet_handlers.c | 271 +++++++++++++\n .../net/ethernet/qualcomm/rmnet/rmnet_handlers.h | 26 ++\n drivers/net/ethernet/qualcomm/rmnet/rmnet_map.h | 88 +++++\n .../ethernet/qualcomm/rmnet/rmnet_map_command.c | 107 ++++++\n .../net/ethernet/qualcomm/rmnet/rmnet_map_data.c | 105 ++++++\n .../net/ethernet/qualcomm/rmnet/rmnet_private.h | 45 +++\n drivers/net/ethernet/qualcomm/rmnet/rmnet_vnd.c | 170 +++++++++\n drivers/net/ethernet/qualcomm/rmnet/rmnet_vnd.h | 29 ++\n include/uapi/linux/if_arp.h | 1 +\n include/uapi/linux/if_ether.h | 3 +\n 17 files changed, 1428 insertions(+)\n create mode 100644 Documentation/networking/rmnet.txt\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/Kconfig\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/Makefile\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_config.c\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_config.h\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_handlers.c\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_handlers.h\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_map.h\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_map_command.c\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_map_data.c\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_private.h\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_vnd.c\n create mode 100644 drivers/net/ethernet/qualcomm/rmnet/rmnet_vnd.h" }
