rt2x00: Allow dynamic addition of PCI/USB IDs.

2011-04-19T19:39:45+00:00

Both USB and PCI drivers allow a system administrator to dynamically add
USB/PCI IDs to the device table that a driver supports via the
/sys/bus/{usb,pci,pci_express}/drivers//new_id files.

However, for the rt2x00 drivers using this method currently crashes the
system with a NULL pointer failure.

This is due to the set-up of rt2x00 where the probe functions require a
rt2x00_ops structure in the driver_info field of the probed device. As
this field is empty for the dynamically added devices this fails for
these devices.

Fix this by introducing driver-specific probe wrappers that do nothing
but calling the bus-specific probe functions with the rt2x00_ops structure
as an argument, rather than depending on the driver_info field.

rt2x00: Decrease association time for USB devices

2011-04-19T19:39:37+00:00

When powersaving is enabled, assocaition times are very high
(for WPA2 networks, the time can easily be around the 3 seconds).

This is caused, because the flushing of the queues takes
too much time. Without the flushing callback mac80211 assumes
a timeout of 100ms while scanning. Limit all flush waiting
loops to the same maximum.

We can apply this maximum by passing the drop status to the
driver, which makes sure the driver performs extra actions
during the waiting for the queue to become empty.

After these changes, association times fall within the
healthy range of ~0.6 seconds with powersaving enabled.
The difference between association time between powersaving
enabled and disabled is now only ~0.1 second (which can also
be due to the measuring method).

rt2x00: Limit rt2x00pci rxdone processing to 16 entries at once

2011-04-04T20:20:01+00:00

Instead of receiving an unlimited number of frames, stop after 16
entries and reschedule the rxdone tasklet. This allows other tasklets
to be run inbetween.

rt2x00: Fix firmware loading regression on x86_64.

2010-12-13T20:23:37+00:00

Commit 6175ddf06b6172046a329e3abfd9c901a43efd2e changes the way
memcpy_toio() works for x86_64, causing firmware loading to fail for
some Ralink WLAN devices with the rt2800pci driver since linux 2.6.34.
This causes the log message: "phy0 -> rt2800pci_load_firmware: Error -
PBF system register not ready.".

Fix this by using __iowrite32_copy instead of memcpy_toio().

rt2x00: Move common txdone handling to rt2x00lib_txdone.

2010-06-30T19:00:50+00:00

Now that the write_tx_data functions are merged, also merge the relevant
parts of the txdone handling into common code, rather than {usb,pci}
specific code.

rt2x00: Merge PCI and USB versions of write_tx_data into single function.

2010-06-30T19:00:50+00:00

Now that rt2x00pci_write_tx_data and rt2x00usb_write_tx_data are similar
we can merge them in a single function in rt2x00queue.c.

rt2x00: Properly reserve room for descriptors in skbs.

2010-06-03T08:51:45+00:00

Instead of fiddling with the skb->data pointer and thereby risking
out of bounds accesses, properly reserve the space needed in an
skb for descriptors.

Extend the write_tx_data callback with a txdesc parameter to allow
access to the tx desciptor while preparing the tx data.

rt2x00: Reorganize RT chipset setting for PCI/SOC devices.

2010-02-15T21:14:10+00:00

Don't set the RT chipset for a device from within the generic PCI/SOC code,
but rather from the individual drivers, so that individual drivers have
more control over what RT chipset is set.

rt2x00: Update copyright statements.

2009-11-11T22:09:17+00:00

As mentioned on the linux-wireless mailing list, the current copyright
statements in the rt2x00 are meaningless, as the rt2x00 project is
not even a formal legal entity. Therefore it is better to replace
the existing copyright statements with copyright statements for the
people that actually wrote the code.

Note: Updated to the best of my knowledge with respect to who
contributed considerable amounts of code.
