Hi Johannes,
Recently I have taken a look at csa switch callback. After looking more
closely I decided to let mac80211 handle this itself, but I noticed
something strange in the interface so maybe you can clarify this.
void (*channel_switch)(struct ieee80211_hw *hw,
struct ieee80211_channel_switch *ch_switch);
void ieee80211_chswitch_done(struct ieee80211_vif *vif, bool success);
Basically we get a channel switch callback for iee80211_hw and for the
ieee80211_chswitch_done() the driver has to provide a vif. Should the
channel switch also operate on a vif?
Ah, well, no, not right now anyway -- mac80211 doesn't support
multi-channel operation yet.
However, I think this kind of hw offload isn't necessary for your device
at all.
Indeed I concluded we do not need this, but I just wanted to clarify the
intended use of the interface.
