When USB Ethernet is plugged in ASMEDIA ASM1042A xHCI host, bad
performance was manifesting in Web browser use (like download

ASM1042A that is not compatible with driver scheduling,
As a workaround we can modify flow control handling of ASM1042A.
The register we modify is changes the behavior

Thanks, looks good, but checkpatch complains about:
+ usleep_range(50, 50);
having same min and max value.
Does usleep_range(40,60) work for you? or some other range?
It works to use usleep_range(40,60);
Thanks for help us to upstream the patch.
I can change that myself, no need to resend.
Matthias,
Can you still get this in for 4.13?
He is on vacation for few weeks.
Perhaps in rcX.
Thanks for the heads up, I wasn't aware since I didn't get back any OOO or
anything like that.
I hope this can make it into one of the rc's indeed then when he returns.
Pushed to my for-usb-linus branch, will send forward to Greg (4.13-rcx) if
branch passes smoke test.
I'm at the office this week, I'll be on vacation again after that for two more
weeks
-Mathias
