I decided to try not sending a DELBA because it is immediately followed by a DEAUTH anyway. The AP will clear block-ack session state in response to DELBA, and delete *all* state in response to DEAUTH. So omitting DELBA should be fine, and eliminates a frame we need to manage to send out successfully in order to roam away. There is an #if 0 in the patch which you can switch to an #if 1 in order to send the DELBA frame if you would like to try that. Not getting a regulatory notification from the firmware does not matter. We do not do anything with such information yet beyond printing it to dmesg in debug mode.
