Some hardware require L2 padding between header and payload because both must be aligned to a 4-byte boundary. This hardware also is easier during the RX path since we no longer need to move the entire payload but rather only the header to remove the padding (mac80211 only wants the payload to be 4-byte aligned).

As discussed on linux-wireless rt2x00 does not offer a true RFKILL key, for that reason RFKILL support should be entirely removed.

Move all code which determines the right TX descriptor fields specific to crypto support into rt2x00crypto.c. This makes the code in rt2x00queue more simpler and better concentrates all crypto code into a single location.

Merge the callback functions init_txentry() and init_rxentry(). This makes life in rt2x00lib a lot simpler and we can cleanup several functions. rt2x00pci contained "fake" FIELD definitions for descriptor words. This is not flexible since it assumes the driver will always have the same field to indicate if a driver is available or not.

With the new configuration handling, and more specifically splitting the configuration of the antenna from the normal configuration steps allowed a BUG_ON() to be triggered in the driver because the SW_DIVERSITY was send to the driver. This fixes that by catching the value early in rt2x00config.c and replacing it with a sensible value. This also fixes a problem where the antenna is not being initialized at all when the radio is enabled. Since it no longer is part of the mac80211 configuration the only place where rt2x00 configured it was the SW diversity handler. Obviously this is broken for all non-diversity hardware and breaks SW diversity due to a broken initialization. When the radio is enabled the antenna will be configured once as soon as the config() callback function is called. Signed-off-by: NIvo van Doorn <IvDoorn@gmail.com> Signed-off-by: NJohn W.

Various rt2x00 devices support hardware encryption. Most of them require the IV/EIV to be generated by mac80211, but require it to be provided seperately instead of within the frame itself. This means that rt2x00lib should extract the data from the frame and place it in the frame descriptor. During RX the IV/EIV is provided in the descriptor by the hardware which means that it should be inserted into the frame by rt2x00lib.

Recent changes to the rate structure registration broke rt2x00, the hw_value was reduced from 32bits to 16bits while rt2x00 used the full 32bits. However the way rt2x00 used the value was inflexible and needed to be changed anyway.

Rework the interface handling. Delete the interface structure and replace it with a per-interface structure. This changes the way rt2x00 handles the active interface drastically. Copy ieee80211_bss_conf to the this rt2x00_intf structure during the bss_info_changed() callback function. This will allow us to reference it later, and removes the requirement for the device flag SHORT_PREAMBLE flag which is interface specific. Drivers receive the option to give the maximum number of virtual interfaces the device can handle. Virtual interface support: rt2400pci: 1 sta or 1 ap, * monitor interfaces rt2500pci: 1 sta or 1 ap, * monitor interfaces rt2500usb: 1 sta or 1 ap, * monitor interfaces rt61pci: 1 sta or 4 ap, * monitor interfaces rt73usb: 1 sta or 4 ap, * monitor interfaces At the moment none of the drivers support AP and STA interfaces simultaneously, this is a hardware limitation so future support will be very unlikely. Each interface structure receives its dedicated beacon entry, with this we can easily work with beaconing while multiple master mode interfaces are currently active. The configuration handlers for the MAC, BSSID and type are often called together since they all belong to the interface configuration. Merge the 3 configuration calls and cleanup the API between rt2x00lib and the drivers. While we are cleaning up the interface configuration anyway, we might as well clean up the configuration handler as well. Signed-off-by: NIvo van Doorn <IvDoorn@gmail.com> Signed-off-by: NJohn W.

This introduces a big queue handling overhaul, this also renames "ring" to "queues". Move queue handling into rt2x00queue.c and the matching header, use Kerneldoc to improve rt2x00 library documentation. Access to the queues is now protected under a spinlock, this to prevent race conditions which could corrupt the indexing system of the queue. Each queue entry allocates x bytes for driver/device specific data, this cleans up the queue structure significantly and improves code readability. rt2500usb no longer needs 2 entries in the beacon queue to correctly send out the guardian byte. This is now handled in the entry specific structure. rt61 and rt73 now use the correct descriptor size for beacon frames, since this data is written into the registers not the entire TXD descriptor was used but instead of a subset of it named TXINFO. Finally this also fixes numerous other bugs related to incorrect beacon handling or beacon related code. Signed-off-by: NIvo van Doorn <IvDoorn@gmail.com> Signed-off-by: NJohn W.
