2015-06-10mac80211: convert HW flags to unsigned long bitmapJohannes Berg
As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

2015-04-24mac80211: remove support for IFF_PROMISCJohannes Berg
This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind. For real monitoring of the network, the monitor mode support should be used instead. Removing it removes a lot of corner cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2014-06-25mac80211: support more than one band in scan requestDavid Spinadel
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.

2014-05-16drivers/net/wireless/ti/wl*/spi.c: Simplify CRC computationGeorge Spelvin
These devices require commands stored in buffers in an odd order, different from that in which the CRC is computed. Rather than make two copies of the commands in two different orders, form the commands in logical (CRC) order, append the CRC, then byte-swap in place to the desired order. The old code worked fine, I'm just scratching an "ugh, that's ugly" itch. Signed-off-by: George Spelvin <linux@horizon.com> Reviewed-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: John W.

2014-01-09wl1251: enforce changed hw encryption support on monitor state changeDavid Gnedt
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.

2014-01-09wl1251: fix scan behaviour while not associatedDavid Gnedt
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.
