The AX88178 has a 10/100/1000 Ethernet MAC with GMII/RGMII interface for interfacing with Gigabit Ethernet PHY. .Pp These devices will operate with both USB 1.x and USB 2.0 controllers, however performance with 1.x controllers will be limited since the USB 1.x standard specifies a maximum transfer speed of 12Mbps. Users with USB 1.x controllers should therefore not expect to actually achieve 100Mbps speeds with these devices. .Pp All chipsets support a 64-bit multicast hash table, single perfect filter entry for the station address, all-multicast mode and promiscuous mode. Packets are received and transmitted over separate USB bulk transfer endpoints. .Pp The .Nm driver supports the following media types: .Bl -tag -width ".Cm 10baseT/UTP" .It Cm autoselect Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to .Xr rc.conf 5 . .It Cm 10baseT/UTP Set 10Mbps operation. The .Xr ifconfig 8 .Cm mediaopt option can also be used to select either .Cm full-duplex or .Cm half-duplex modes. .It Cm 100baseTX Set 100Mbps (Fast Ethernet) operation. The .Xr ifconfig 8 .Cm mediaopt option can also be used to select either .Cm full-duplex or .Cm half-duplex modes. .It Cm 1000baseT Set 1000Mbps (Gigabit Ethernet) operation (AX88178 only). The .Xr ifconfig 8 .Cm mediaopt option can also be used to select either .Cm full-duplex or .Cm half-duplex modes. .El .Pp The .Nm driver supports the following media options: .Bl -tag -width ".Cm full-duplex" .It Cm full-duplex Force full duplex operation. .It Cm half-duplex Force half duplex operation. .El .Pp For more information on configuring this device, see .Xr ifconfig 8 . .Sh HARDWARE The .Nm driver supports ASIX Electronics AX88172/AX88178/AX88772/AX88772A/AX88772B/AX88760 based USB Ethernet adapters including: .Pp AX88172: .Bl -bullet -compact .It AboCom UF200 .It Acer Communications EP1427X2 .It ASIX AX88172 .It ATen UC210T .It Billionton SnapPort .It Billionton USB2AR .It Buffalo (Melco Inc.)
