rt2x00: trim skb_frame_desc to 32 bytes Remove frame_type from skb_frame_desc and pass it as argument to rt2x00debug_dump_frame(). Change data_len and desc_len to unsigned short to save another 4 bytes in skb_frame_desc. Note that this was the only location where the data_len and desc_len was not yet treated as unsigned short. This trim is required to help mac80211 with adding the TX control and TX status informtation into the skb->cb structure. When that happens, drivers will have approximately 40 bytes left to use freely. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

[PATCH] rt2x00: Fix rfkill handling As reported by Modestas Vainius, enabling rkfill in 1 driver and disabling it in a second could cause a NULL pointer exception when the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag. Furthermore, rfkill expects the timeout as a value in milliseconds instead of jiffies. Also increase the timeout to a second, since this 250ms would be overkill. Also the flag DEVICE_ENABLED_RADIO_HW is causing problems for devices which do not support the hardware button while rfkill is enabled in the driver. To remidy this we should inverse the flag and its meaning, rename the flag to DEVICE_DISABLED_RADIO_HW this means that by default the radio is enabled by the hardware button (if present) and can only be disabled explicitely.

rt2x00: Rate structure overhaul 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. This patch creates a array containing information for each rate, the hw_value passed to mac80211 is the index value for that array including a field to indicate if short preamble should be enabled.

rt2x00: Add per-interface structure 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.

rt2x00: Fix BUG_ON() with antenna handling 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: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
