[PATCH 1/9] rt2x00: Support hardware RTS and CTS-to-self frames

[PATCH 1/9] rt2x00: Support hardware RTS and CTS-to-self frames

[Ivo van Doorn]

If the driver has set the set_rts_threshold() callback function
to mac80211 it is capable of generating RTS and CTS-to-self frames
inside the hardware and rt2x00lib doesn't have to create them
in software.
Only rt2800pci and rt2800usb support this feature.

[PATCH 2/9] rt2x00: Remove DRIVER_SUPPORT_MIXED_INTERFACES

[Ivo van Doorn]

A lot more is needed to support mixed interfaces then just this flag,
such things need new redesigns in rt2x00lib to actually make it happen.
So far there doesn't exist a Ralink chipset that can handle it, so
we might as well remove the flag for now and see what should be done
whenever a device appears that can handle it.

[PATCH 3/9] rt2x00: Don't enable short preamble for 1MBs

[Ivo van Doorn]

The timing settings for 1MBs should exclude
the short preamble bit since that only applies
to 2MBs, 5.5MBs and 11MBs.

[PATCH 4/9] rt2x00: Use rt2x00 queue numbering

[Ivo van Doorn]

Use the rt2x00 queue enumeration as much as possible,
removing the usage of the mac80211 queue numbering
wherever it is possible.

This makes it easier for mac80211 to change it queue
identification scheme without having to deal with
big changes in the rt2x00 code.

[PATCH 5/9] rt2x00: Fix quality/activity led handling

[Ivo van Doorn]

There was an obvious typo in LED structure
initialization which caused the radio and quality/activity
leds to be incorrectly initialized which resulted in
the leds not being enabled.

Additionally add the rt2x00led_led_activity() handler
that will enable TX/RX activity leds when the radio
is being enabled.

[PATCH 6/9] rt2x00: Clarify supported chipsets in Kconfig

[Ivo van Doorn]

As reported by Filipus Klutiero <chealer@gmail.com>,
the rt2x00 Kconfig entries should be updated with
specific chipset notifications.

This cleans up Kconfig by explicitly mentioning the
supported chipsets for each drivers, and uses the
same chipset family names as mentioned on the Ralink website.

Cool, thanks a lot. One small note:

Are you actually using TX_QUEUE_AFTER_BEACON? That queue number is a
historical accident (imho) and not used, we actually use the
IEEE80211_TXCTL_SEND_AFTER_DTIM tx control flag.

Also, with the QoS patch, those queue numbers should finally go away and
mac80211 will not pass anything but the data queues, hence, this small
inline would probably be reduced to "return queue;" by the patch.

Actually both the checks for IEEE80211_TX_QUEUE_BEACON and IEEE80211_TX_QUEUE_AFTER_BEACON
are fake and only present for completeness.
rt2x00 does check for IEEE80211_TXCTL_SEND_AFTER_DTIM and will resolve it to QID_ATIM
if that queue is supported by the hardware (rt2400pci and rt2500pci) and resolves it to the control->queue
in all other cases.

This function only exists to move the translation in a single location.
When the translation isn't needed anymore because skb_get_queue_mapping(skb)
or something else is used, then this function can be removed completely. :)

Well there are two cases.

(1) MQ is not configured -> it always returns 0
(2) MQ is configured, mac80211 will create a device with hw->queues
queues, so it'll be in the range [0 .. hw->queues-1]

Ps. Can I assume that skb_get_queue_mapping(skb) or whatever replacement
for control->queue will make sure the given queue will not exceed the max
number of supported queues as configured by the driver (through hw->queues)?

Or should the driver drop such packets or resolve it to the highest queue available?

Excellent.
That means the same assumptions can be made about the queue parameter
as with the old solution. :)
