Move the default mesh beacon interval and DTIM period to cfg80211 and
make it accessible to nl80211. This enables setting both values when joining
an MBSS.
NOTE: In a mesh with links in PS mode it is not advised to use the default
parameters 1000:4, as these cause excessive buffering delays that exceed
various timeouts (e.g. HWMP path request).
Then make the default parameters reasonable? How is 1000:2?
That's still ~2 seconds, no?
Yeah I guess those would both be unsuitable for PS anyway, so it's fine as is.
Snap, I just see carl9170 has a check for beacon interval and DTIM
period [1].
I'll change the DTIM period default value.
To my best knowledge, it does not do any difference out of powersave
mode, and for powersave DTIM period 1 is favourable. Any objections?

(CARL9170_QUEUE_STUCK_TIMEOUT is 5500.)
