USB: zaurus: Add ID for A-300/B-500/C-700

2023-08-01T21:44:27+00:00

The SL-A300, B500/5600, and C700 devices no longer auto-load because of "usbnet: Remove over-broad module alias from zaurus." This patch adds IDs for those 3 devices.

net: usb: cdc_ether: add u-blox 0x1313 composition.

2023-07-01T12:15:58+00:00

Add CDC-ECM support for LARA-R6 01B. The new LARA-R6 product variant identified by the "01B" string can be configured (by AT interface) in three different USB modes: * Default mode (Vendor ID: 0x1546 Product ID: 0x1311) with 4 serial interfaces * RmNet mode (Vendor ID: 0x1546 Product ID: 0x1312) with 4 serial interfaces and 1 RmNet virtual network interface * CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1313) with 4 serial interface and 1 CDC-ECM virtual network interface The first 4 interfaces of all the 3 configurations (default, RmNet, ECM) are the same. In CDC-ECM mode LARA-R6 01B exposes the following interfaces: If 0: Diagnostic If 1: AT parser If 2: AT parser If 3: AT parset/alternative functions If 4: CDC-ECM interface Signed-off-by: Davide Tronchin Reviewed-by: Simon Horman Signed-off-by: David S.

cdc_ether: no need to blacklist any r8152 devices

2023-01-09T07:39:53+00:00

The r8152 driver does not need this anymore. Dropping blacklist entries adds optional support for these devices in ECM mode. The 8153 devices are handled by the r8153_ecm driver when in ECM mode, and must still be blacklisted here. Signed-off-by: Bjørn Mork Signed-off-by: David S. Miller

net: usb: cdc_ether: add support for Thales Cinterion PLS62-W modem

2023-01-06T06:04:58+00:00

This modem has 7 interfaces, 5 of them are serial interfaces and are driven by cdc_acm, while 2 of them are wwan interfaces and are driven by cdc_ether: If 0: Abstract (modem) If 1: Abstract (modem) If 2: Abstract (modem) If 3: Abstract (modem) If 4: Abstract (modem) If 5: Ethernet Networking If 6: Ethernet Networking Without this change, the 2 network interfaces will be named to usb0 and usb1, our QA think the names are confusing and filed a bug on it. After applying this change, the name will be wwan0 and wwan1, and they could work well with modem manager.

r8152: add PID for the Lenovo OneLink+ Dock

2022-08-27T15:35:41+00:00

The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as a broken CDC device by default. Add the custom Lenovo PID to the r8152 driver to support it properly. Also, systems compatible with this dock provide a BIOS option to enable MAC address passthrough (as per Lenovo document "ThinkPad Docking Solutions 2017"). Add the custom PID to the MAC passthrough list too. Tested on a ThinkPad 13 1st gen with the expected results: passthrough disabled: Invalid header when reading pass-thru MAC addr passthrough enabled: Using pass-thru MAC addr XX:XX:XX:XX:XX:XX Signed-off-by: Jean-Francois Le Fillatre Signed-off-by: David S.

cdc_ether: export usbnet_cdc_zte_rx_fixup

2022-04-14T13:08:12+00:00

Commit bfe9b9d2df66 ("cdc_ether: Improve ZTE MF823/831/910 handling") introduces a workaround for certain ZTE modems reporting invalid MAC addresses over CDC-ECM. The same issue was present on their RNDIS interface,which was fixed in commit a5a18bdf7453 ("rndis_host: Set valid random MAC on buggy devices"). However, internal modem of ZTE MF286R router, on its RNDIS interface, also exhibits a second issue fixed already in CDC-ECM, of the device not respecting configured random MAC address. In order to share the fixup for this with rndis_host driver, export the workaround function, which will be re-used in the following commit in rndis_host.
