Re: [PATCH 1/1] mac80211: Add support connection monitor in hardware

Hi,

I think you are mixing up the two sets of patches which I'm working on,
which seem to have ended up with confusingly similar names. Sorry about
that.

The connection quality monitoring stuff is configurable via nl80211.
This feature, the connection monitoring in hardware, is only configured
via the mac80211 flag IEEE80211_HW_CONNECTION_MONITOR, so no netlink
configuration here.

The main difference in functionality between hw and host connection
monitoring is, I think, power consumption - the host cpu needs to work
less if the hardware is handling this.
