Please pull 'upstream' branch of rt2x00

[Ivo van Doorn]

Hi John,

Here is the 2.1.2 release of rt2x00. Several important bugfixes like a
partial return of TX/RX activity in the PCI drivers.

Note that _none_ of the drivers (PCI or USB) are in a good shape since the
2.1.0 release. With partial RX/TX activity we are at least now on a similar
behavior as the 2.0.14 version inside kernel 2.6.25.

Speaking of the 2.6.25 kernel, it seems that rt2x00 is not in an all too good
shape in there. If more reports about broken TX/RX come in I will consider
reverting a lot of patches to make rt2x00 look a lot like the version in 2.6.24.
That version wasn't good either, but at least people can't complain about
regressions. ;)

Also note that the git pull request below also contains the patches from
previous pull request. But I noticed that you hadn't pulled in the 2.1.1 release yet.
I won't resent those patches to the list, since there aren't any changes in them
since last week. ;)

Ivo

[PATCH 01/11] rt2x00: Send frames out with configured TX power

[Ivo van Doorn]

mac80211 sends the txpower to use during config(),
we already store it in the rt2x00_dev structure.
When writing the descriptor correctly initialize
the txpower field with this value to make sure
all frames are send out with the correct tx power.

[PATCH 02/11] rt2x00: Don't report driver generated frames to tx_status()

[Ivo van Doorn]

This adds a new flag for the skb_frame_desc structure which is used to tag
rts/cts frames that are generated by the driver. Through the tag we can
recognize frames we have generated ourselves, so we don't report their tx
status to mac80211.

This patch is based on the original patch by
Mattias Nissler <mattias.nissler@gmx.de>.

[PATCH 04/11] rt2x00: Filter ACK_CTS based on FIF_CONTROL

[Ivo van Doorn]

The ACK_CTS frame is a control frame, this means
dropping the frame depends on the FIF_CONTROL flag
for filtering.

This also fixes an obvious typo in register definition.

[PATCH 03/11] rt2x00: Fix Descriptor DMA initialization

[Ivo van Doorn]

As Adam Baker reported the DMA address for the
descriptor base was incorrectly initialized in
the PCI drivers.

Instead of the DMA base for the descriptor, the
DMA base for the data was passed resulting in a
broken TX/RX state for PCI drivers.

[PATCH 05/11] rt2x00: Remove reset_tsf()

[Ivo van Doorn]

Specifications indicate the TSF registers are read-only,
so there is no point in writing 0 to those registers.

As far as I know there isn't another way to reset the
TSF registers. So removing these callbacks will notify
mac80211 about the lack of support.

[PATCH 06/11] rt2x00: Rename dscape -> mac80211

[Ivo van Doorn]

The dscape stack was renamed to mac80211 a long time ago,
we are long overdue with fixing all comments to reflect this.

[PATCH 07/11] rt2x00: Cleanup mode registration

[Ivo van Doorn]

Don't wildly pass any number for num_rates to rt2x00lib,
instead pass which type of rates are supported (CCK, OFDM).
Same for num_modes but then for the 2GHZ and 5GHZ band.

This makes the interface look much nicer and makes
extending it later easier.

[PATCH 08/11] rt2x00: Remove async vendor request calls from rt2x00usb

[Ivo van Doorn]

The async vendor requests are a ugly hack which is not working correctly.
The proper fix for the scheduling while atomic issue is finding out why
we can't use led classes for USB drivers and fix that.

Just replace all async calls with the regular ones and print an
error for the disallowed LED configuration attempts. That will
help in determining which led class is causing the problem.

[PATCH 09/11] Fix hw mode registration with mac80211.

[Ivo van Doorn]

From: Gertjan van Wingerde <gwingerde@kpnplanet.nl>

The supported_bands field of struct hw_mode_spec now represents a bitfield,
so bitfield operators need to be tested with when setting the band data.

The current code generates the following warning:

[PATCH 10/11] rt2x00: Fix MAC address defines in rt61pci

[Ivo van Doorn]

The MAC address offset defines were incorrect because
the byte offset was used instead of word index. This
bug had no affect on normal operations since these
defines weren't used. (EEPROM_MAC_ADDR_0 was used
to read 6 bytes from).
