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, AR9287, AR9380, AR9390, AR9580, AR9590, AR9562 and QCA9565 chips (and companion RF/baseband parts). This code is part of the ath(4) driver but configured separately to allow fine-grained control over the set of chips supported. Selecting ath_hal 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.

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.

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.
