Every single time, I see: * the TID isn't scheduled; * The software queue for that TID has the first and last seqno in the BAW in the software queue (along with other frames here and there); * .. i _think_ the HW transmission has failed, so the frames appear again in the SWQ; * .. but it's thus not being rescheduled. I'll post further information soon. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
