cfg80211 events

cfg80211 events

[Daniel Wolstenholme]

Hi all,

I'm working with the Broadcom brcmfmac driver, and I'm attempting to improve
event reporting, but I'm finding there's not that much documentation on
wireless events.  One big problem I'm having is that I'm using the cfg80211
interface, but when I run "iw event -t -f", I don't see the events showing
up.  Another question I have is: is there a way to send events with
arbitrary strings from the driver through to userspace?

Any pointers would be greatly appreciated.

Dan

I'd be careful of that; we don't want a repeat of IWPRIV events, we'd
rather have stuff standardized.  Unless you're doing this for testing,
of course.

Indeed. You can use testmode events for in-house testing, qualification,
calibration, etc. but it will be compiled out in distro kernels.

Arbitrary string events will never exist.

Hi Dan,

Just curious, on what kind of hardware platform are you using brcmfmac?

Thanks,
Franky
