It fixes FW crashes that disrupt throughput and connectivity in general in very popular devices (Intel's WiFi 7000 and 8000 series). I know it's a bit late for v5.2, but if possible, it would be great to take this. Kalle is on vacation, so we agreed that I would send it directly to you. Please let me know if this is okay or if we should send this to -next and get it into v5.2 via stable releases instead. Thanks! -- Cheers, Luca.
