# NAME

axen — ASIX Electronics AX88178a/AX88179 10/100/Gigabit USB Ethernet device

# SYNOPSIS

axen* at uhub? port ?
rgephy* at mii?

# DESCRIPTION

The axen driver provides support for USB Ethernet adapters based on the ASIX Electronics AX88178a and AX88779 USB 2.0 chipsets (potentially the AX88779 supports USB 3.0, but there is currently no xhci support in NetBSD), including the following:

Kurotoshiko GbE-USB3.0
Logitec LAN-GTJU3
Shanghai Donya DN-84327

The axen driver supports the following media types:

autoselect
  Enable autoselection of the media type and options (this is the default). The user can manually override the autoselected mode by adding media options to the appropriate ifconfig.if(5) file.
10baseT
  Set 10Mbps operation.
100baseTX
  Set 100Mbps (Fast Ethernet) operation.
1000baseT
  Set 1000Mbps (Gigabit Ethernet) operation.

For more information on configuring this device, see ifconfig(8).
