---------------------------
What: b43 support for firmware revision < 410
When: July 2008
When: The schedule was July 2008, but it was decided that we are going to keep the
code as long as there are no major maintanance headaches.
So it _could_ be removed _any_ time now, if it conflicts with something new.
Why: The support code for the old firmware hurts code readability/maintainability
and slightly hurts runtime performance. Bugfixes for the old firmware
are not provided by Broadcom anymore.

---help---
A driver for 802.11b wireless cards based on the "Hermes" or
Intersil HFA384x (Prism 2) MAC controller. This includes the vast
majority of the PCMCIA 802.11b cards (which are nearly all rebadges)
- except for the Cisco/Aironet cards. Cards supported include the
Apple Airport (not a PCMCIA card), WavelanIEEE/Orinoco,
Cabletron/EnteraSys Roamabout, ELSA AirLancer, MELCO Buffalo, Avaya,
IBM High Rate Wireless, Farralon Syyline, Samsung MagicLAN, Netgear
MA401, LinkSys WPC-11, D-Link DWL-650, 3Com AirConnect, Intel
IPW2011, and Symbol Spectrum24 High Rate amongst others.
This option includes the guts of the driver, but in order to
actually use a card you will also need to enable support for PCMCIA
Hermes cards, PLX9052 based PCI adaptors or the Apple Airport below.
You will also very likely also need the Wireless Tools in order to
configure your card and that /etc/pcmcia/wireless.opts works :

config HERMES_CACHE_FW_ON_INIT

default y
---help---
Say Y to cache any firmware required by the Hermes drivers
on startup. The firmware will remain cached until the
driver is unloaded. The cache uses 64K of RAM.
Otherwise load the firmware from userspace as required. In
this case the driver should be unloaded and restarted
whenever the firmware is changed.
If you are not sure, say Y.
config APPLE_AIRPORT
tristate "Apple Airport support (built-in)"
depends on PPC_PMAC && HERMES
help
Say Y here to support the Airport 802.11b wireless Ethernet hardware
built into the Macintosh iBook and other recent PowerPC-based
Macintosh machines. This is essentially a Lucent Orinoco card with
a non-standard interface.
This driver does not support the Airport Extreme (802.11b/g). Use
the BCM43xx driver for Airport Extreme cards.
config PLX_HERMES

depends on PCI && HERMES
help
Enable support for PCMCIA cards supported by the "Hermes" (aka
orinoco) driver when used in PLX9052 based PCI adaptors. These
adaptors are not a full PCMCIA controller but act as a more limited
PCI <-> PCMCIA bridge. Several vendors sell such adaptors so that
802.11b PCMCIA cards can be used in desktop machines. The Netgear
MA301 is such an adaptor.

tristate "Prism 2.5 PCI 802.11b adaptor support"
depends on PCI && HERMES
help
Enable support for PCI and mini-PCI 802.11b wireless NICs based on
the Prism 2.5 chipset. These are true PCI cards, not the 802.11b
PCMCIA cards bundled with PCI<->PCMCIA adaptors which are also
common. Some of the built-in wireless adaptors in laptops are of
this variety.
config PCMCIA_HERMES
tristate "Hermes PCMCIA card support"
depends on PCMCIA && HERMES
---help---
A driver for "Hermes" chipset based PCMCIA wireless adaptors, such
as the Lucent WavelanIEEE/Orinoco cards and their OEM (Cabletron/
EnteraSys RoamAbout 802.11, ELSA Airlancer, Melco Buffalo and
others). It should also be usable on various Prism II based cards
such as the Linksys, D-Link and Farallon Skyline. It should also
work on Symbol cards such as the 3Com AirConnect and Ericsson WLAN.
You will very likely need the Wireless Tools in order to
configure your card and that /etc/pcmcia/wireless.opts works:

This is a driver for 802.11b cards using RAM-loadable Symbol
firmware, such as Symbol Wireless Networker LA4100, CompactFlash
cards by Socket Communications and Intel PRO/Wireless 2011B.
This driver requires firmware download on startup. Utilities
