From: Matti Gottlieb <matti.gottlieb@xxxxxxxxx>
During the sequence of exchanging GAS frames with the AP, the AP can
request to comeback in X amount of time and resend the GAS request.
Currently the wpa_supplicant does not initiate the termination of the
remain-on-channel session, but rather waits until the requested comeback
delay has expired, and then tries to send the GAS frame (potentially
to save the time that is required to schedule a new remain on channel
flow).
This might cause unnecessary idle time (can be close to 1000 ms) in which the
device might be off-channel. Ending the current remain-on-channel session and
then rescheduling makes better usage of the time in this case.
End remain-on-channel session due to receiving a delayed GAS comeback request
from the AP.
