I can confirm that this patch fixes the crashing issue. That said, I’m still able to get faster speeds from an AX210 wifi card. I’m only able to get ~300Mbit upload and ~500Mbit download on 5Ghz and 6Ghz, but had a weird issue on 6Ghz where initially I was getting ~2Mbit but upon reconnecting it got back up to ~500Mbit.
Note I tested this using linux-mainline on Arch with ~5 patches applied including this one; the others were needed for this change to merge correctly. I’ll post the details later for anyone interested.
