2017-11-15cdc_ncm: Set NTB format again after altsetting switch for Huawei devicesEnrico Mioso
commit 2b02c20ce0c28974b44e69a2e2f5ddc6a470ad6f upstream. Some firmwares in Huawei E3372H devices have been observed to switch back to NTB 32-bit format after altsetting switch. This patch implements a driver flag to check for the device settings and set NTB format to 16-bit again if needed. The flag has been activated for devices controlled by the huawei_cdc_ncm.c driver. V1->V2: - fixed broken error checks - some corrections to the commit message V2->V3: - variable name changes, to clarify what's happening - check (and possibly set) the NTB format later in the common bind code path Signed-off-by: Enrico Mioso <mrkiko.rs@gmail.com> Reported-and-tested-by: Christian Panton <christian@panton.org> Reviewed-by: Bjørn Mork <bjorn@mork.no> CC: Bjørn Mork <bjorn@mork.no> CC: Christian Panton <christian@panton.org> CC: linux-usb@vger.kernel.org CC: netdev@vger.kernel.org CC: Oliver Neukum <oliver@neukum.org> Signed-off-by: David S.

2016-12-02cdc_ether: Fix handling connection notificationKristian Evensen
Commit bfe9b9d2df66 ("cdc_ether: Improve ZTE MF823/831/910 handling") introduced a work-around in usbnet_cdc_status() for devices that exported cdc carrier on twice on connect. Before the commit, this behavior caused the link state to be incorrect. It was assumed that all CDC Ethernet devices would either export this behavior, or send one off and then one on notification (which seems to be the default behavior). Unfortunately, it turns out multiple devices sends a connection notification multiple times per second (via an interrupt), even when connection state does not change. This has been observed with several different USB LAN dongles (at least), for example 13b1:0041 (Linksys). After bfe9b9d2df66, the link state has been set as down and then up for each notification. This has caused a flood of Netlink NEWLINK messages and syslog to be flooded with messages similar to: cdc_ether 2-1:2.0 eth1: kevent 12 may have been dropped This commit fixes the behavior by reverting usbnet_cdc_status() to how it was before bfe9b9d2df66. The work-around has been moved to a separate status-function which is only called when a known, affect device is detected. v1->v2: * Do not open-code netif_carrier_ok() (thanks Henning Schild). * Call netif_carrier_off() instead of usb_link_change(). This prevents calling schedule_work() twice without giving the work queue a chance to be processed (thanks Bjørn Mork).

2016-10-31r8152: Fix broken RX checksums.Mark Lord
The r8152 driver has been broken since (approx) 3.16.xx when support was added for hardware RX checksums on newer chip versions. Symptoms include random segfaults and silent data corruption over NFS. The hardware checksum logig does not work on the VER_02 dongles I have here when used with a slow embedded system CPU. Google reveals others reporting similar issues on Raspberry Pi. So, disable hardware RX checksum support for VER_02, and fix an obvious coding error for IPV6 checksums in the same function. Because this bug results in silent data corruption, it is a good candidate for back-porting to -stable >= 3.16.xx. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: David S.

2016-10-13qmi_wwan: add support for Quectel EC21 and EC25Bjørn Mork
The Quectel EC21 and EC25 need the same "set DTR" request as devices based on the MDM9230 chipset, but has no USB3 support. Our best guess is that the "set DTR" functionality depends on chipset and/or baseband firmware generation. But USB3 is still an optional feature. Since we cannot enable this unconditionally for all older devices, and there doesn't appear to be anything we can use in the USB descriptors to identify these chips, we are forced to use a device specific quirk flag.

2016-09-06lan78xx: mark symbols static where possibleBaoyou Xie
We get a few warnings when building kernel with W=1: drivers/net/usb/lan78xx.c:1182:6: warning: no previous prototype for 'lan78xx_defer_kevent' [-Wmissing-prototypes] drivers/net/usb/lan78xx.c:1409:5: warning: no previous prototype for 'lan78xx_nway_reset' [-Wmissing-prototypes] drivers/net/usb/lan78xx.c:2000:5: warning: no previous prototype for 'lan78xx_set_mac_addr' [-Wmissing-prototypes] .... In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. so this patch marks these functions with 'static'.

Macros that end in an underscore are just odd. Add hso_dbg(level, fmt, ...) and use it everwhere instead. Several uses had additional unnecessary newlines as the macro added a newline.
