Hi Johannes,
But they shouldn't change due a mac address change? I wonder if we can
further relax the requirements to allow mac change if
NL80211_SCAN_FLAG_RANDOM_ADDR was used?
No, at least with HW scan that would completely confuse the driver -
since from the driver's POV we'd remove the interface it's currently
managing the scan for.
So help me understand this better.
include/net/mac80211.h:
int (*hw_scan)(struct ieee80211_hw *hw, struct ieee80211_vif *vif,
struct ieee80211_scan_request *req);
How is it difficult to understand that with an API like that, it might
not be a good idea to remove the vif from the driver while it's
scanning?
Right, so you're talking in the context of this implementation which
performs a remove/add interface. You're right about that.
But I was asking more in general terms. If all we're doing is scanning,
can we just change the mac? Anyway, not important. Maybe I bring this
up once this set is accepted.
