2022-06-10USB: Follow-up to SPDX GPL-2.0+ identifiers addition - remove now useless ↵Christophe JAILLET
comments All these files have been updated in the commit given in the Fixes: tag below. When the SPDX-License-Identifier: has been added, the corresponding text at the beginning of the files has not been deleted. All these texts are about GPL-2.0+, with different variation in the wording. Remove these now useless lines to save some LoC. Fixes: 5fd54ace4721 ("USB: add SPDX identifiers to all remaining files in drivers/usb/") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2022-04-14rndis_host: enable the bogus MAC fixup for ZTE devices from cdc_etherLech Perczak
Certain ZTE modems, namely: MF823. MF831, MF910, built-in modem from MF286R, expose both CDC-ECM and RNDIS network interfaces. They have a trait of ignoring the locally-administered MAC address configured on the interface both in CDC-ECM and RNDIS part, and this leads to dropping of incoming traffic by the host. However, the workaround was only present in CDC-ECM, and MF286R explicitly requires it in RNDIS mode. Re-use the workaround in rndis_host as well, to fix operation of MF286R module, some versions of which expose only the RNDIS interface. Do so by introducing new flag, RNDIS_DRIVER_DATA_DST_MAC_FIXUP, and testing for it in rndis_rx_fixup. This is required, as RNDIS uses frame batching, and all of the packets inside the batch need the fixup. This might introduce a performance penalty, because test is done for every returned Ethernet frame. Apply the workaround to both "flavors" of RNDIS interfaces, as older ZTE modems, like MF823 found in the wild, report the USB_CLASS_COMM class interfaces, while MF286R reports USB_CLASS_WIRELESS_CONTROLLER.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

2012-05-12usb/net: rndis: break out <linux/rndis.h> definesLinus Walleij
As a first step to consolidate the RNDIS implementations, break out a common file with all the #defines and move it to <linux/rndis.h>. This also deletes the immediate duplicated defines in the <linux/rndis.h> file that yields a lot of compilation warnings.

2012-05-12usb/net: rndis: inline the cpu_to_le32() macroLinus Walleij
The header file <linux/usb/rndis_host.h> used a number of #defines that included the cpu_to_le32() macro to assure the result will be in LE endianness. Inlining this into the code instead of using it in the code definitions yields consolidation opportunities later on as you will see in the following patches. The individual drivers also used local defines - all are switched over to the pattern of doing the conversion at the call sites instead.

2011-04-13rndis_host: Poll status before control channel where necessaryBen Hutchings
Some RNDIS devices don't respond on the control channel until polled on the status channel. In particular, this was reported to be the case for the 2Wire HomePortal 1000SW and for some Windows Mobile devices. This is roughly based on a patch by John Carr <john.carr@unrouted.co.uk> which is currently applied by Mandriva.

For the header files in include/linux/usb, add missing multiple inclusion protection and standardize what's already there.

Move headers usbnet.h and rndis_host.h to include/linux/usb and fix includes for drivers/net/usb modules. Headers are moved because rndis_wlan will be outside drivers/net/usb in drivers/net/wireless and yet need these headers.
