Add driver support for the Aironet 4500/4800 series wireless 802.11

NICs. (Finally!) The PCMCIA, ISA and PCI varieties are all supported,
though only the ISA and PCI ones will work on the alpha for now.
PCCARD, ISA and PCI attachments are all provided. Also provided an
ancontrol(8) utility for configuring the NIC, man pages, and updated
pccard.conf.sample. ISA cards are supported in both ISA PnP and hard-wired
mode, although you must configure the kernel explicitly to support the
hardwired mode since you have to know the I/O address and port ahead
of time.

Special thanks to Doug Ambrisko for doing the initial newbus hackery
and getting it to work in infrastructure mode.

+Aironet Communications 4500/4800 wireless network adapter driver
+.Sh SYNOPSIS
+.Cd "device an0"
+.Cd "device an0 at isa? port 0x140 net irq 5"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for Aironet Communications 4500 and 4800
+wireless network adapters. This includes the ISA, PCI and PCMCIA
+varieties. The 4500 series adapters operate at 1 and 2Mbps while
+the 4800 series can operate at 1, 2, 5.5 and 11Mbps. The ISA, PCI
+and PCMCIA devices are all based on the same core PCMCIA modules
+and all have the same programming interface, however unlike the
+Lucent WaveLAN/IEEE cards, the ISA and PCI cards appear to the
+host as normal ISA and PCI devices and no not require any PCCARD
+support.
+.Pp
+The PCMCIA Aironet cards require pccard support, including the
+kernel pccard driver support and the
+.Xr pccardd 8
+daemon. ISA cards can either be configured to use ISA Plug and Play
+or to use a particular I/O address and IRQ
+by properly setting the DIP switches on the board. (The default
+switch setting is for plug and play.) The
+.Nm
+driver has Plug and Play support and will work in either configuration,
+however when using a hard-wired I/O address and IRQ, the driver
+configuration and the NIC's switch settings must agree. PCI cards
+require no switch settings of any kind and will be automatically
+probed and attached.
+.Pp
+All host/device interaction with the Aironet cards is via programmed I/O.
+The Aironet devices support 802.11 and 802.3 frames, power management,
+BSS (infrastructure) and IBSS (ad-hoc) operation modes. The
+.Nm
+driver encapsulates all IP and ARP traffic as 802.11 frames, however
+it can receive either 802.11 or 802.3 frames. Transmit speed is
+selectable between 1Mbps, 2Mbps, 5.5Mbps, 11Mbps or
+"auto" (the NIC automatically chooses the best speed).
+.Pp
+By default, the
+.Nm
+driver configures the Aironet card for ad-hoc operation with an SSID
+of "ANY." In this mode,
+stations can communicate among each other without the aid of an access
+point. To join a service set, the driver must be set for BSS mode using
+the
+.Xr ancontrol 8
+utility.
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "an%d: init failed"
+The Aironet card failed to come ready after an initialization command was
+issued.
+.It "an%d: failed to allocate %d bytes on NIC"
+The driver was unable to allocate memory for transmit frames in the
+NIC's on-board RAM.
+.It "an%d: device timeout"
+The Aironet card failed to generate an interrupt to acknowledge a transmit
+command.
