mac80211: support more than one band in scan request Some drivers (such as iwlmvm) can handle multiple bands in a single HW scan request. Add a HW flag to indicate that the driver support this. To hold the required data, create a separate structure for HW scan request that holds cfg scan request and data about different parts of the scan IEs. As this changes the mac80211 API, update all drivers using it to use the correct new function type/argument.

Revert "wl1251: enforce changed hw encryption support on monitor state change" This reverts commit b90a1165a72fabdc260abaa9eeadcbfd29e267eb. That commit (or rather, hack) triggers a scary WARN in IBSS (ad-hoc) mode.

wl1251: enforce changed hw encryption support on monitor state change The firmware doesn't support per packet encryption selection, so disable hw encryption support completely while a monitor interface is present to support injection of packets (which shouldn't get encrypted by hw). To enforce the changed hw encryption support force a disassociation on non-monitor interfaces. For disassociation a workaround using hw connection monitor is employed, which temporary enables hw connection manager flag.

wl1251: fix scan behaviour while not associated With a dissasociated card I often encoutered very long scan delays. My guess is that it has something to do with the cards DTIM handling and another firmware bug mentioned in the TI WLAN driver, which is described as the card may never end scanning if the channel is overloaded because it can't send probe requests. I think the firmware somehow also tries to receive DTIM messages when the BSSID is not set. Therefore most of the time it waits for DTIM messages and can't do scanning work. Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY bit for scans in disassociated state.

wl1251: fix filtering support This driver has a hack in cmd.c which effectively disables all filtering. This seems to be triggering a firmware bug where it stops reporting any rx packets after random time on some routers, which is eliminated (or at least appears much more rarely) when filtering is on. I have found that only BSSID filter needs to be disabled for association to work, so disable only that instead of all filtering.
