if the already present interface is an incompatible
interface. for example in ath9k we don't advertise ADHOC in
ieee80211_iface_combination structure in the driver,
so it can only exist as an single interface
I'm not sure I understand what you're changing here?
if an interface say ad-hoc is not advertised in iface combination,
with the current still we can add that interface with some other
interface(removing the driver checks).
in ath9k we have
static const struct ieee80211_iface_limit if_limits[] = {
{ .max = 2048, .types = BIT(NL80211_IFTYPE_STATION) |
BIT(NL80211_IFTYPE_P2P_CLIENT) |
BIT(NL80211_IFTYPE_WDS) },
{ .max = 8, .types =
#ifdef CONFIG_MAC80211_MESH
BIT(NL80211_IFTYPE_MESH_POINT) |
#endif
BIT(NL80211_IFTYPE_AP) |
BIT(NL80211_IFTYPE_P2P_GO) },
};
i am able to create an IBSS interface even if a STA interface is up and
running in ath9k(removing the driver checks).
this patch ensures that if we have an incompatible interface, it is the
only one can that can exist.
*if the driver is not advertising interface combination just
return so that we don't break their multivif operation.
Actually, we want to break multivif for drivers that don't advertise it.
oh, ok.
