The axe
driver provides support for USB
Ethernet adapters based on the ASIX Electronics AX88172, AX88178, and
AX88772 USB 2.0 chipsets, including the following:
The AX88172, AX88178, and AX88772 are USB 2.0 devices designed to work with either Ethernet or HomePNA transceivers. The AX88172 and AX88772 contain 10/100 Ethernet MACs with MII interfaces. The AX88178 contains a 10/100/Gigabit Ethernet MAC with a GMII/MII interface. All adapters will operate with either USB 1.x or 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.
A 64-bit multicast hash table is supported, 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.
The axe
driver supports the following
media types:
The axe
driver supports the following
media options:
The interface will operate in half-duplex mode if no media option is specified.
