.Cd "device ath_ar9287"
.Cd "options AH_SUPPORT_AR5416"
.Sh DESCRIPTION
The hal provides hardware support for wireless network adapters based on
the Atheros AR5210, AR5211, AR5212, AR5213, AR2413, AR2417, AR2425,
AR5413, AR5416, AR5418, AR5424, AR9160, AR9220, AR9280, AR9285 and AR9287
chips (and companion RF/baseband parts).
This code is part of the
.Xr ath 4
driver but configured separately to allow fine-grained control
over the set of chips supported.
Selecting
.Nm
enables support for all PCI and Cardbus devices.
Note this includes AR5416, AR5418, AR9130, AR9160, AR9220, AR9280, AR9285
and AR9287 devices and must be accompanied by the
AH_SUPPORT_AR5416
option to enable the extended hardware descriptor format used by
AR5416 and later devices.
.Pp
Some devices come in Cardbus/MiniPCI/PCI format.
Others (for example AR2413, AR2427, AR5418, AR9280, AR9285, AR9287) come in
PCIe, Mini-PCIe or ExpressCard format.
.Pp
Historically this code has been released in a binary-only form
and packaged as a separate module.
With the release of source code for the hal this is no longer true
and the code is tightly integrated with the driver.
