so its v3.7 tag hash 29594404d7fe73cd80eaa4ee8c43dcc53970c60e.
i see that code line :). thanks
i traced a while and looked at the rt2500pci.c code and there we are
assigning the max_ap_intf variable to 1. the same go with the
rt2800pci.c
here's the part of the ops structure
static const struct rt2x00_ops rt2500pci_ops = {
.name = KBUILD_MODNAME,
.max_ap_intf = 1,
.eeprom_size = EEPROM_SIZE,
.rf_size = RF_SIZE,
.tx_queues = NUM_TX_QUEUES,
.extra_tx_headroom = 0,
.rx = &rt2500pci_queue_rx,
.tx = &rt2500pci_queue_tx,
.bcn = &rt2500pci_queue_bcn,
.atim = &rt2500pci_queue_atim,
.lib = &rt2500pci_rt2x00_ops,
.hw = &rt2500pci_mac80211_ops,
#ifdef CONFIG_RT2X00_LIB_DEBUGFS
.debugfs = &rt2500pci_rt2x00debug,
#endif /* CONFIG_RT2X00_LIB_DEBUGFS */
};
i really dont know why is that max_ap_intf is 1. may be some wireless
dev's know about this?
