Meet a TFS subelement ID unknown issue while fast roaming [CYW43455]

[LeonH]

Hi ,

We meet a roaming issue: wifi disconnection happens very often.
Issue happen rate: around once per 2 hour

AP: Aruba

STA : CYW43455+RK3326

OS: Android 8

Wifi Driver: DHD

wl0: Sep 26 2020 15:23:44 version 7.45.173 (r707987 CY) FWID 01-668b6f11

I find a error: TFS subelement ID unknown (65) 

Is it a root cause for disconnect?

How could we fix it? or it just concerns router compatible.

Hello:

    Would you please share a sniffer log that includes the disconnection process?  and it is better to get the dmesg or supplicant together if possible.

Hi Zhengbao,

Sorry~sniffer log is too large to upload it.

And dmesg is confidential, I already created mycase for upload.

Hello Leon:

 if the issue was resolved already ?  thanks.

This packet means error/malformed, maybe the packet can't be captured in a correct way because of the environment, no other meanings,  it is better to capture correct packets for the analysis.
