Adds support in mac80211 for NL80211_EXT_FEATURE_POWERED_ADDR_CHANGE. The motivation behind this functionality is to fix limitations of address randomization on frequencies which are disallowed in world roaming. The way things work now, if a client wants to randomize their address per-connection it must power down the device, change the MAC, and power back up. Here lies a problem since powering down the device may result in frequencies being disabled (until the regdom is set). If the desired BSS is on one such frequency the client is unable to connect once the phy is powered again. For mac80211 based devices changing the MAC while powered is possible but currently disallowed (-EBUSY). This patch adds some logic to allow a MAC change while powered by removing the interface, changing the MAC, and adding it again. mac80211 will advertise support for this feature so userspace can determine the best course of action e.g. disallow address randomization on certain frequencies if not supported. There are certain limitations put on this which simplify the logic: - No active connection - No offchannel work, including scanning. Signed-off-by:

Add a new extended feature bit signifying that the wireless hardware supports changing the MAC address while the underlying net_device is powered. Note that this has a different meaning from IFF_LIVE_ADDR_CHANGE as additional restrictions might be imposed by the hardware, such as: - No connection is active on this interface, carrier is off - No scan is in progress - No offchannel operations are in progress Signed-off-by:

There some bounds checking to ensure that "map_addr" is not out of bounds before the start of the loop. But the checking needs to be done as we iterate through the loop because "map_addr" gets larger as we iterate. Fixes: 26f1fad2 ("New driver: rtl8xxxu (mac80211)") Signed-off-by:

We turn off interrupt in ISR, and re-enable interrupt in threadfn or napi_poll according to the mode it stays. If we are turning off interrupt, rtwpci->running flag is unset and interrupt handler stop processing even if it was called, so disallow to re-enable interrupt in this situation. Or, wifi chip doesn't trigger interrupt events anymore because interrupt status (ISR) isn't clear by interrupt handler anymore.

When starting to send heavy traffic in low power mode, driver will call multiple tx wake notify to wake firmware within a short time. In this situation, firmware may miss power mode change request from driver and leads to status error. So we change driver to call power_mode_change at most three times to make sure firmware could get the request. Signed-off-by:

Sometimes, BB might encounter RX problem on OFDM 6M. It's not quite easy to happen, but if it happens, we will keep getting stuck on RX. And, since we cannot properly receive layer 2 ACK, it also casues TX problem, e.g. constantly retrying TX. Eventually, after some time, we would get disconnected due to abnormal behavior. Update break setting and phy status parsing time to make BB get out of stuck state faster. Signed-off-by:
