On 6.11, it seems there are a few API updates we need to take care of:
Something called a "return thunk":

kernel: warning: `Socket Thread' uses wireless extensions which will stop
working for Wi-Fi 7 hardware; use nl80211
```
And not sure if that "Socket Thread" warning is a consequence of any of
the above warnings.
I have not tried this out long enough to see if it has real
consequences, but as usual it would be great to fix these. But fwiw, it
seems these are harmless _for now_.
I do not plan to try patching these anytime soon since they are not
"urgent" (it seems). But I might get to them later, at the very least to
keep these cards working on trixie :).
Cheers.
