Yes, please do it! The faster it gets mainline, the more people will benefit from the fix. As far as I recall, some months ago someone asked me to submit the patch using git mail or something like that, which I did for the first time. It command reported success, but I did not get any replays since then from anyone. I intended to resubmit it the following week, but got overwhelmed by tasks, and the time passed. Meanwhile I still keep the patch in GitHub/httpstorm/openwrt, brach gvalkov. No changes are required since the original e-mail, so it can be submitted to mainline.

There is another issue with my iPhone 7 Plus, which is unrelated to this patch:
If an iPhone is tethered to a MacBook, the next time it gets connected to an OpenWRT router the USB Ethernet interface appears, but there is no communication. Hence I would assume this unrelated issue also has to be fixed in another patch. I can confirm that in this state macOS and Windows are able to use USB tethering, only OpenWRT is affected. So far I found the following workarounds:
* reboot the phone or run:
* usbreset 002/002 && /etc/init.d/usbmuxd restart

The same happens if the phone reboots due to extreme cold temperatures while tethered. Finally there is also a bug or possible hardware/baseband fault in my phone where every few days the modem reboots: the LTE icon disappears for a few seconds, and tethering is turned off. Either way, running the commands mentioned above re-enable tethering and restore the communication instantly. It would be nice if a watchdog is integrated in ipheth to trigger recovery automatically.
