The preferred module is p54pci which also supports FullMAC
PCI / Cardbus devices. We schedule removal for 2.6.34. Reason
to remove this is no one really is testing prism54 anymore,
and while it works p54pci provides support for the same hardware.
It should be noted I have been told some FullMAC devices may not
have worked with the SoftMAC driver but to date we have yet to
recieve a single bug report regarding this. If there are users
out there please let us know!

Change that and also tell firmware about disabled QoS, so it

The calculated values for the ACK timeout and ACK
consume time are different then the values as
used by the Legacy drivers.

After testing from James Ledwith it appeared that
the calculated values caused a high amount of TX
failures, and the values from the Legacy drivers
were the most optimal to prevent TX failure due to
excessive retries.

The symptoms of this problem:
 - Rate control module always falls back to 1Mbs
 - Low throughput when bitrate was fixed

Possible side-effects (not confirmed but highly likely)
 - Problems with DHCP
 - Broken connections due to lack of probe response

This should fix at least:
Kernel bugzilla reports: [13362], [13009], [9273]
Fedora bugzilla reports: [443203]
but possible some additional bugs as well.

This patch adds a classful dummy scheduler which can be used as root qdisc
for multiqueue devices and exposes each device queue as a child class.

This allows to address queues individually and graft them similar to regular
classes. Additionally it presents an accumulated view of the statistics of
all real root qdiscs in the dummy root.

Two new callbacks are added to the qdisc_ops and qdisc_class_ops:

- cl_ops->select_queue selects the tx queue number for new child classes.

- qdisc_ops->attach() overrides root qdisc device grafting to attach
  non-shared qdiscs to the queues.

Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Currently the multiqueue integration with the qdisc API suffers from
a few problems:

- with multiple queues, all root qdiscs use the same handle. This means
  they can't be exposed to userspace in a backwards compatible fashion.

- all API operations always refer to queue number 0. Newly created
  qdiscs are automatically shared between all queues, its not possible
  to address individual queues or restore multiqueue behaviour once a
  shared qdisc has been attached.

- Dumps only contain the root qdisc of queue 0, in case of non-shared
  qdiscs this means the statistics are incomplete.

This patch reintroduces dev->qdisc, which points to the (single) root qdisc
from userspace's point of view. Currently it either points to the first
(non-shared) default qdisc, or a qdisc shared between all queues. The
following patches will introduce a classful dummy qdisc, which will be used
as root qdisc and contain the per-queue qdiscs as children.

Some schedulers don't support creating, changing or deleting classes.
Make the respective callbacks optionally and consistently return
-EOPNOTSUPP for unsupported operations, instead of currently either
-EOPNOTSUPP, -ENOSYS or no error.

In case of sch_prio and sch_multiq, the removed operations additionally
checked for an invalid class. This is not necessary since the class
argument can only orginate from ->get() or in case of ->change is 0
for creation of new classes, in which case ->change() incorrectly
returned -ENOENT.

As a side-effect, this patch fixes a possible (root-only) NULL pointer
function call in sch_ingress, which didn't implement a so far mandatory
->delete() operation.
