This is in fact not
registration from user namespaces.

The wmediumd Netlink portid is tracked per net namespace. Additionally,
the portid is stored on all radios created in that net namespace to
simplify the portid lookup in the data path.

exception is NL80211_CMD_SET_WIPHY, which explicitly uses a namespace aware

* On namespace exit, do not destroy hwsim radios originally created in
the initial network namespace.

Hi,
We are experiencing some issues when running ath10k in AP mode.
Unfortunately, I didn't manage to reproduce the issue in the lab, but
in the field we see it roughly once a day on one out of fifty devices.
The symptoms are the logged "SWBA overruns" followed by a kernel

I have no hard numbers, as I have
more testing with this approach before considering to
upstream it.

Subject: [PATCH] ath10k: Schedule hardware restart if WMI command times out
and their interfaces.
Add netlink announcements through nl80211 when switching namespaces,
so userspace can rely on these events to discover radios properly.
