wireless: mark prism54 as deprecated and mark for removal
Browse files Browse the repository at this point in the history
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!

What: PRISM54
When: 2.6.34

Why: prism54 FullMAC PCI / Cardbus devices used to be supported only by the
prism54 wireless driver. After Intersil stopped selling these
devices in preference for the newer more flexible SoftMAC devices
a SoftMAC device driver was required and prism54 did not support
them. The p54pci driver now exists and has been present in the kernel for
a while. This driver supports both SoftMAC devices and FullMAC devices.
The main difference between these devices was the amount of memory which
could be used for the firmware. The SoftMAC devices support a smaller
amount of memory. Because of this the SoftMAC firmware fits into FullMAC
devices's memory. p54pci supports not only PCI / Cardbus but also USB
and SPI. Since p54pci supports all devices prism54 supports
you will have a conflict. I'm not quite sure how distributions are
handling this conflict right now. prism54 was kept around due to
claims users may experience issues when using the SoftMAC driver.
Time has passed users have not reported issues. If you use prism54
and for whatever reason you cannot use p54pci please let us know!

If you enable this you will need a firmware file as well.
You will need to copy this to /usr/lib/hotplug/firmware/isl3890.
You can get this non-GPL'd firmware file from the Prism54 project page:
<http://prism54.org>
You will also need the /etc/hotplug/firmware.agent script from
a current hotplug package.

Note: You need a motherboard with DMA support to use any of these cards

If you want to compile the driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/kbuild/modules.txt>.
The module will be called prism54.
This enables support for FullMAC PCI/Cardbus prism54 devices. This
driver is now deprecated in favor for the SoftMAC driver, p54pci.
p54pci supports FullMAC PCI/Cardbus devices as well. For details on
the scheduled removal of this driver on the kernel see the feature
removal schedule:

Documentation/feature-removal-schedule.txt

When built as module you get the module prism54
