vxlan: move to its own directory

2022-03-01T08:38:01Z

vxlan.c has grown too long. This patch moves it to its own directory. subsequent patches add new functionality in new files. Signed-off-by: Roopa Prabhu Signed-off-by: David S. Miller

amt: add control plane of amt interface

2021-11-01T13:36:08Z

It adds definitions and control plane code for AMT. this is very similar to udp tunneling interfaces such as gtp, vxlan, etc. In the next patch, data plane code will be added. Signed-off-by: Taehee Yoo Signed-off-by: David S. Miller

net: mhi: Remove MBIM protocol

2021-08-04T09:10:12Z

The MBIM protocol has now been integrated in a proper WWAN driver. We can then revert back to a simpler driver for mhi_net, which is used for raw IP or QMAP protocol (via rmnet link). - Remove protocol management - Remove WWAN framework usage (only valid for mbim) - Remove net/mhi directory for simpler mhi_net.c file Signed-off-by: Loic Poulain Signed-off-by: David S.

make legacy ISA probe optional

2021-08-03T12:05:26Z

There are very few ISA drivers left that rely on the static probing from drivers/net/Space.o. Make them all select a new CONFIG_NETDEV_LEGACY_INIT symbol, and drop the entire probe logic when that is disabled. The 9 drivers that are called from Space.c are the same set that calls netdev_boot_setup_check(). Signed-off-by: Arnd Bergmann Signed-off-by: David S. Miller

mctp: Add initial driver infrastructure

net: Add a WWAN subsystem

2021-04-16T22:31:02Z

This change introduces initial support for a WWAN framework. Given the complexity and heterogeneity of existing WWAN hardwares and interfaces, there is no strict definition of what a WWAN device is and how it should be represented. It's often a collection of multiple devices that perform the global WWAN feature (netdev, tty, chardev, etc). One usual way to expose modem controls and configuration is via high level protocols such as the well known AT command protocol, MBIM or QMI. The USB modems started to expose them as character devices, and user daemons such as ModemManager learnt to use them. This initial version adds the concept of WWAN port, which is a logical pipe to a modem control protocol. The protocols are rawly exposed to user via character device, allowing straigthforward support in existing tools (ModemManager, ofono...). The WWAN core takes care of the generic part, including character device management, and relies on port driver operations to receive/submit protocol data. Since the different devices exposing protocols for a same WWAN hardware do not necessarily know about each others (e.g. two different USB interfaces, PCI/MHI channel devices...) and can be created/removed in different orders, the WWAN core ensures that all WAN ports contributing to the 'whole' WWAN feature are grouped under the same virtual WWAN device, relying on the provided parent device (e.g. mhi controller, USB device). It's a 'trick' I copied from Johannes's earlier WWAN subsystem proposal. This initial version is purposely minimalist, it's essentially moving the generic part of the previously proposed mhi_wwan_ctrl driver inside a common WWAN framework, but the implementation is open and flexible enough to allow extension for further drivers.

dsa: simplify Kconfig symbols and dependencies

2021-03-22T19:15:37Z

1. Remove CONFIG_HAVE_NET_DSA. CONFIG_HAVE_NET_DSA is a legacy leftover from the times when drivers should have selected CONFIG_NET_DSA manually. Currently, all drivers has explicit 'depends on NET_DSA', so this is no more needed. 2. CONFIG_HAVE_NET_DSA dependencies became CONFIG_NET_DSA's ones. - dropped !S390 dependency which was introduced to be sure NET_DSA can select CONFIG_PHYLIB. DSA migrated to Phylink almost 3 years ago and the PHY library itself doesn't depend on !S390 since commit 870a2b5e4fcd ("phylib: remove !S390 dependeny from Kconfig"); - INET dependency is kept to be sure we can select NET_SWITCHDEV; - NETDEVICES dependency is kept to be sure we can select PHYLINK. 3. DSA drivers menu now depends on NET_DSA. Instead on 'depends on NET_DSA' on every single driver, the entire menu now depends on it. This eliminates a lot of duplicated lines from Kconfig with no loss (when CONFIG_NET_DSA=m, drivers also can be only m or n). This also has a nice side effect that there's no more empty menu on configurations without DSA. 4. Kbuild will now descend into 'drivers/net/dsa' only when CONFIG_NET_DSA is y or m. This is safe since no objects inside this folder can be built without DSA core, as well as when CONFIG_NET_DSA=m, no objects can be built-in.

net: mhi: Add dedicated folder

2021-02-10T23:11:51Z

Create a dedicated mhi directory for mhi-net, mhi-net is going to be split into differente files (for additional protocol support). Signed-off-by: Loic Poulain Signed-off-by: David S. Miller

net: Add mhi-net driver

2020-11-06T00:54:01Z

This patch adds a new network driver implementing MHI transport for network packets. Packets can be in any format, though QMAP (rmnet) is the usual protocol (flow control + PDN mux). It support two MHI devices, IP_HW0 which is, the path to the IPA (IP accelerator) on qcom modem, And IP_SW0 which is the software driven IP path (to modem CPU).

wimax: move out to staging

2020-10-29T18:27:45Z

There are no known users of this driver as of October 2020, and it will be removed unless someone turns out to still need it in future releases. According to https://en.wikipedia.org/wiki/List_of_WiMAX_networks, there have been many public wimax networks, but it appears that many of these have migrated to LTE or discontinued their service altogether. As most PCs and phones lack WiMAX hardware support, the remaining networks tend to use standalone routers. These almost certainly run Linux, but not a modern kernel or the mainline wimax driver stack. NetworkManager appears to have dropped userspace support in 2015 https://bugzilla.gnome.org/show_bug.cgi?id=747846, the www.linuxwimax.org site had already shut down earlier. WiMax is apparently still being deployed on airport campus networks ("AeroMACS"), but in a frequency band that was not supported by the old Intel 2400m (used in Sandy Bridge laptops and earlier), which is the only driver using the kernel's wimax stack. Move all files into drivers/staging/wimax, including the uapi header files and documentation, to make it easier to remove it when it gets to that. Only minimal changes are made to the source files, in order to make it possible to port patches across the move. Also remove the MAINTAINERS entry that refers to a broken mailing list and website.
