[PATCH v3] nl80211: Driver capability retrieval only once the interface is UP

[Sreenath S]

Hello Johannes,

What you have told is correct and this is not a mandatory patch. I just felt it is logical to do interface UP before capability retrieval, similar to the older approach before P2P_DEVICE integration.

Regards,
Sreenath

Which driver has a problem with this? cfg80211/nl80211 is not intended
to be used in a way that defers the capability advertisement after the
interface is UP, the advertised values are expected to be correct before
the interface is up. As such, I don't see how with a properly written
driver this patch can be required.
