2017-06-07qmi_wwan: add another Lenovo EM74xx device IDBjørn Mork1-0/+2
[ Upstream commit 486181bcb3248e2f1977f4e69387a898234a4e1e ] In their infinite wisdom, and never ending quest for end user frustration, Lenovo has decided to use a new USB device ID for the wwan modules in their 2017 laptops. The actual hardware is still the Sierra Wireless EM7455 or EM7430, depending on region. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

2017-05-20cdc_ncm: do not call usbnet_link_change from cdc_ncm_bindBjørn Mork1-15/+5
commit 4d06dd537f95683aba3651098ae288b7cbff8274 upstream. usbnet_link_change will call schedule_work and should be avoided if bind is failing. Otherwise we will end up with scheduled work referring to a netdev which has gone away. Instead of making the call conditional, we can just defer it to usbnet_probe, using the driver_info flag made for this purpose.

2016-07-12cdc_ncm: toggle altsetting to force reset before setupBjørn Mork1-1/+5
[ Upstream commit 48906f62c96cc2cd35753e59310cb70eb08cc6a5 ] Some devices will silently fail setup unless they are reset first. This is necessary even if the data interface is already in altsetting 0, which it will be when the device is probed for the first time. Briefly toggling the altsetting forces a function reset regardless of the initial state. This fixes a setup problem observed on a number of Huawei devices, appearing to operate in NTB-32 mode even if we explicitly set them to NTB-16 mode.

Instead it uses a Huawei specific scheme: functions are mapped by subclass and protocol. However, the HP vendor ID is used for modems from many different manufacturers using different schemes, so we cannot apply a generic vendor rule like we do for the Huawei vendor ID. Replace the previous lt4112 entry pointing to an arbitrary interface number with a device specific subclass + protocol match.

[ Upstream commit 7a1e890e2168e33fb62d84528e996b8b4b478fea ] cdc_ncm disagrees with usbnet about how much framing overhead should be counted in the tx_bytes statistics, and tries 'fix' this by decrementing tx_bytes on the transmit path. But statistics must never be decremented except due to roll-over; this will thoroughly confuse user-space. Also, tx_bytes is only incremented by usbnet in the completion path.

2014-11-07asix: Do full reset during ax88772_bindCharles Keepax1-13/+1
commit 3cc81d85ee01 ("asix: Don't reset PHY on if_up for ASIX 88772") causes the ethernet on Arndale to no longer function. This appears to be because the Arndale ethernet requires a full reset before it will function correctly, however simply reverting the above patch causes problems with ethtool settings getting reset. It seems the problem is that the ethernet is not properly reset during bind, and indeed the code in ax88772_bind that resets the device is a very small subset of the actual ax88772_reset function. This patch uses ax88772_reset in place of the existing reset code in ax88772_bind which removes some code duplication and fixes the ethernet on Arndale. It is still possible that the original patch causes some issues with suspend and resume but that seems like a separate issue and I haven't had a chance to test that yet.

2014-10-20ax88179_178a: fix bonding failureIan Morgan1-1/+6
The following patch fixes a bug which causes the ax88179_178a driver to be incapable of being added to a bond. When I brought up the issue with the bonding maintainers, they indicated that the real problem was with the NIC driver which must return zero for success (of setting the MAC address). I see that several other NIC drivers follow that pattern by either simply always returing zero, or by passing through a negative (error) result while rewriting any positive return code to zero. With that same philisophy applied to the ax88179_178a driver, it allows it to work correctly with the bonding driver. I believe this is suitable for queuing in -stable, as it's a small, simple, and obvious fix that corrects a defect with no other known workaround. This patch is against vanilla 3.17(.0).

Pull networking updates from David Miller: "Most notable changes in here: 1) By far the biggest accomplishment, thanks to a large range of contributors, is the addition of multi-send for transmit. This is the result of discussions back in Chicago, and the hard work of several individuals. Now, when the ->ndo_start_xmit() method of a driver sees skb->xmit_more as true, it can choose to defer the doorbell telling the driver to start processing the new TX queue entires. skb->xmit_more means that the generic networking is guaranteed to call the driver immediately with another SKB to send. There is logic added to the qdisc layer to dequeue multiple packets at a time, and the handling mis-predicted offloads in software is now done with no locks held. Finally, pktgen is extended to have a "burst" parameter that can be used to test a multi-send implementation. Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4, virtio_net Adding support is almost trivial, so export more drivers to support this optimization soon. I want to thank, in no particular or implied order, Jesper Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann, David Tat, Hannes Frederic Sowa, and Rusty Russell. 2) PTP and timestamping support in bnx2x, from Michal Kalderon. 3) Allow adjusting the rx_copybreak threshold for a driver via ethtool, and add rx_copybreak support to enic driver. From Govindarajulu Varadarajan. 4) Significant enhancements to the generic PHY layer and the bcm7xxx driver in particular (EEE support, auto power down, etc.) from Florian Fainelli. 5) Allow raw buffers to be used for flow dissection, allowing drivers to determine the optimal "linear pull" size for devices that DMA into pools of pages. The objective is to get exactly the necessary amount of headers into the linear SKB area pre-pulled, but no more. The new interface drivers use is eth_get_headlen(). From WANG Cong, with driver conversions (several had their own by-hand duplicated implementations) by Alexander Duyck and Eric Dumazet. 6) Support checksumming more smoothly and efficiently for encapsulations, and add "foo over UDP" facility. From Tom Herbert. 7) Add Broadcom SF2 switch driver to DSA layer, from Florian Fainelli. 8) eBPF now can load programs via a system call and has an extensive testsuite. Alexei Starovoitov and Daniel Borkmann. 9) Major overhaul of the packet scheduler to use RCU in several major areas such as the classifiers and rate estimators. From John Fastabend. 10) Add driver for Intel FM10000 Ethernet Switch, from Alexander Duyck. 11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric Dumazet. 12) Add Datacenter TCP congestion control algorithm support, From Florian Westphal. 13) Reorganize sk_buff so that __copy_skb_header() is significantly faster.

2014-10-04asix: Don't reset PHY on if_up for ASIX 88772Michel Stam1-1/+1
I've noticed every time the interface is set to 'up,', the kernel reports that the link speed is set to 100 Mbps/Full Duplex, even when ethtool is used to set autonegotiation to 'off', half duplex, 10 Mbps. It can be tested by: ifconfig eth0 down ethtool -s eth0 autoneg off speed 10 duplex half ifconfig eth0 up Then checking 'dmesg' for the link speed.

USB hub has started to use a workqueue instead of kthread. Let's update the documentation and comments here and there. This patch mostly just replaces "khubd" with "hub_wq". There are only few exceptions where the whole sentence was updated.
