Instead of hardcoding the used in/out endpoints
we should detect them by walking through all

rt2800usb will gain the most out of this, because
the legacy drivers indicate that there are multiple
endpoints available.
However this code might benefit at least rt73usb as
well for the MIMO queues, and if we are really lucky
rt2500usb will benefit because for the TX and PRIO
queues.
Even if rt2500usb and rt73usb do not get better performance

The callback function write_tx_data() can only fail
when our ENTRY_OWNER_DEVICE_DATA flag on a queue entry
failed to determine the entry was not available and
it is in fact still owned by the hardware.
This means that if that function fails the queue
must be stopped in mac80211.
When rt2x00queue_get_queue() returns NULL in the TX
path, it means mac80211 has passed us an invalid queue,
although this should be impossible, it shouldn't hurt
if we send mac80211 a signal to stop the queue either.
Both issues can simply be resolved by removing their
manual failure handler and making them use the failure path
provided in rt2x00mac_tx().

the swiotlb from its 64MB amount of bounce buffers. We remain
consistent and now always use sc->rxbufsize for RX. While at
it we update the beacon DMA maps as well to only use the data
portion of the skb, previous to this we were pci_map_single()'ing
more data for beaconing than what we tell the hardware it can use,
therefore pushing more iotlb abuse.
Still not sure why this is so easily triggerable on
MacBook Pro 3.1, it may be the hardware configuration
tends to use more memory > 3GB mark for DMA.

I asked around, and he's right, there may be platforms that do not allow
passing such such an address to the DMA API functions. This patch
changes it by using the proper dma_sync_single_range_for_cpu API
invented for this purpose.

PHY is mostly compatible with the existing VSC8244 PHY. The init sequence
is different and the interrupt mask lacks some bits present in the VSC8244.
Rather than making a copy of the existing VSC234x config_intr function and
change one constant, I modify it to select the interrupt mask based on
which driver is calling it. This lets it be used by both drivers.

Hi,
after noticing that my Netgear FA411 (PCMCIA-NIC) [1] stopped working with
the release of the 2.6.25 kernel (sidux-version), I checked the
respective driver sources and noticed that the pcnet_cs driver bailed
out with "use axnet_cs instead" for the Netgear FA411, but axnet_cs
doesn't claim this ID.
I compiled a kernel with the PCMCIA-ID for the netgear card moved to
axnet_cs from pcnet_cs which worked. I then contacted sidux-kernel
maintainer Stefan Lippers-Hollmann who turned the info into this patch
and integrated it into the kernel:
<http://svn.berlios.de/svnroot/repos/fullstory/linux-sidux-2.6/trunk/debian/patches/features/2.6.27.4_PCMCIA_move-PCMCIA-ID-for-Netgear-FA411-from-pcnet_cs-to-axnet_cs.patch>
This works for me and AFAIK there were no reports of any breakage for
other devices on sidux-support.
This looks like a trivial patch, but since I have very limited
experience with kernel modifications I might be woefully wrong there.
But if there are no side effects of this patch, is it possible to get it
into the official kernel?
I can provide more detailed information on the affected hardware if
necessary.

commit simply relocates the code to lib80211 and adjusts the drivers
appropriately.

Indirect registers require multiple calls to the CSR
register in order to access the indirect registers.
This must be protected under a lock to prevent race
conditions which could cause invalid data to
be returned when reading from the indirect register or silent
failures when writing data to the indirect register.
USB drivers where already protected under a mutex,
so rename the mutex and make PCI drivers use the mutex
as well.
This now means that BBP and RF registers are no longer
accessible in interrupt context. That is not a bad
situation since the slow behavior of accessing
those registers means we don't _want_ to access them
in interrupt context either.

We can optimize get_duration and get_duration_res
by making them a macro. They are really simple
calculation handlers so this doesn't matter much.
Often (especially in rt2400pci and rt2500pci,
the arguments are hardcoded, and the result value
is passed into other hardcoded values.
By making the functions a macro GCC can
optimize the entire thing much better.

ARRAY_SIZE is more concise to use when the size of an array is divided by
the size of its type or the size of its first element.
The semantic patch that makes this change is as follows:

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.
This should be dependent on the driver, and we
should add a callback function for this.

The RCSR default value for single frame mode is off (a RB contains more than
one frames). But the driver assumes single frame mode apparently. This patch
enables single frame mode for the hardware. It also adds a BUG_ON to make sure
the allocated skb satisfies the hardware alignment requirement and removes
a useless check.
