| 55.Ed 56.Sh DESCRIPTION 57The 58.Nm 59driver provides support for wireless network adapters based on 60the Atheros AR5210, AR5211, AR5212, AR5416 and AR9300 programming APIs. 61These APIs are used by a wide variety of chips; most all chips with 62a PCI, PCIe and/or CardBus interface are supported. 63.Pp 64Supported features include 802.11 and 802.3 frames, power management, BSS, 65IBSS, MBSS, WDS/DWDS TDMA, and host-based access point operation modes. 66All host/device interaction is via DMA. 67.Pp | 53.Ed 54.Sh DESCRIPTION 55The 56.Nm 57driver provides support for wireless network adapters based on 58the Atheros AR5210, AR5211, AR5212, AR5416 and AR9300 programming APIs. 59These APIs are used by a wide variety of chips; most all chips with 60a PCI, PCIe and/or CardBus interface are supported. 61.Pp 62Supported features include 802.11 and 802.3 frames, power management, BSS, 63IBSS, MBSS, WDS/DWDS TDMA, and host-based access point operation modes. 64All host/device interaction is via DMA. 65.Pp |
| 68Please note that from FreeBSD-9.0, the 69.Nm 70driver does not include the PCI/PCIe bus glue. 71The same driver supports multiple underlying bus types, including PCI/PCIe, 72but also embedded (AHB) and USB in the future. 73.Pp 74To enable use for PCI/PCIe systems, see the 75.Xr ath_pci 4 76driver. 77For embedded systems which use the AHB to connect the wireless MAC, see the 78.Xr ath_ahb 4 79driver. 80.Pp | |
