Hi Jouni, thank you so much for the reply.
I have tried to put some traces in the code to detect if it is executing
that function and I have no results. Basing on HS 2.0 R2 specification the
WNM-Notification should be sent after the AP receive an Access-Accept
message from AAA server with the RADIUS attribute
"HS2.0-Subscription-Remediation" (vendor specific attribute from the WFA).
Because of that I have been finding the trigger that makes that function
run, because I was not able to see the function execution after the 4 way
handshake (with the corresponding HS 2.0 parameter in the Access-Accept).
I will check again the execution flow to try to fix this issue.
Thank you again for the support Jouni.
