Re: [PATCH net,stable] net: cdc_mbim: add "NDP to end" quirk for Huawei E3372

Hello guys. I am sorry the way my feature is actually implemented is limiting MUX performances in mbim case, even with good devices. When I developed it, I also probably tought this wasn't affecting MBIM devices. Thank you Bjorn, great work in handling it. Thank you for all of you; Thank you for

[PATCH 1/2] USB: bcma: make helper creating platform dev more generic

Having "bool ohci" argument in bcma_hcd_create_pdev function limited it to support two cases only (OHCI and EHCI) and put too much logic in it. Lets make caller pass all required data. This adds few extra arguments to the function call but will allow us to reuse this code and handle more cases in t

[PATCH 2/2] USB: bcma: separate code initializing USB 2.0 core

This splits one big probing function into two smaller ones. The main one is now responsible for the generic stuff: allocating memory & enabling power using GPIO. The new one contains code that is specific to the USB 2.0 bcma core. This will allow adding support for the USB 3.0 bcma core (handling X

[PATCH net,stable] net: cdc_mbim: add "NDP to end" quirk for Huawei E3372

The Huawei E3372 (12d1:157d) needs this quirk in MBIM mode as well. Allow this by forcing the NTB to contain only a single NDP, and add a device specific entry for this ID. Due to the way Huawei use device IDs, this might be applied to other modems as well. It is assumed that those modems will be

(4.3.0) r8152: deadlock related to runtime suspend?

Hi, I rarely use a Realtek USB 3.0 Gigabit Ethernet adapter (vid/pid 0bda:8153), but when I did last night, it resulted in a lockup of processes doing networking ("ip link", "ping", "ethtool", ...). A (few) minute(s) before that event, I noticed that there was no network connectivity (ping hung)
