Hi all,
We found that Intel 9000 series wifi cards have tx performance issue
on 5G network.
Here are the test result.
Client(10.101.46.25) is the platform with 9260 wifi card on 5G
network, and server(10.101.46.219) is another machine with ethernet
network.
kernel v4.15-rc5 with firmware API 33

Any ideas?
Best regards,

Yes, I'll update my issue there.
Thanks.

Hi all,
Forgot to append the device info, here it is.
02:00.0 Network controller [0280]: Intel Corporation Device [8086:2526] (rev 29)
Subsystem: Intel Corporation Device [8086:4010]
