Does this mean that iface combination definitions are wrong? For example:
static const struct
ieee80211_iface_combination mwifiex_iface_comb_ap_sta_drcs = {
.limits = mwifiex_ap_sta_limits,
.num_different_channels = 2,
.n_limits = ARRAY_SIZE(mwifiex_ap_sta_limits),
.max_interfaces = MWIFIEX_MAX_BSS_NUM,
.beacon_int_infra_match = true,
};
