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!

Currently, when QoS-disable is requested, we would leave QoS enabled

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.

apply the conformance test limits (CTL) stored in the eeprom upon
the values calculated for the tx power (ar->power_*).

This is based on the implementation in the vendor driver
(hal/hpmain.c, line 3700 ff.) with one difference:
If any ctl mode isn't found in the eeprom, we fall back to the "lower",
legacy modes (5GHT20,11A or 2GHT20,11G,11B). Otus only did 5GHT20->11A.

Currently CTL are applied for the FCC group only.

This patch adds support for legacy SJA1000 CAN controllers on the ISA
or PC-104 bus. The I/O port or memory address and the IRQ number must
be specified via module parameters:

  insmod sja1000_isa.ko port=0x310,0x380 irq=7,11

for ISA devices using I/O ports or:

  insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11

for memory mapped ISA devices.

Indirect access via address and data port is supported as well:

  insmod sja1000_isa.ko port=0x310,0x380 indirect=1 irq=7,11

Here is a full list of the supported module parameters:

  port:I/O port number (array of ulong)
  mem:I/O memory address (array of ulong)
  indirect:Indirect access via address and data port (array of byte)
  irq:IRQ number (array of int)
  clk:External oscillator clock frequency (default=16000000 [16 MHz])
      (array of int)
  cdr:Clock divider register (default=0x48 [CDR_CBP | CDR_CLK_OFF])
      (array of byte)
  ocr:Output clock register (default=0x18 [OCR_TX0_PUSHPULL])
      (array of byte)

Note: for clk, cdr, ocr, the first argument re-defines the default
for all other devices, e.g.:

 insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000

is equivalent to

 insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 \
                       clk=24000000,24000000
