🦋 AUE(4) 🦋 — ADMtek AN986 Pegasus USB Fast Ethernet driver

okay so this is the aue(4) page from the Kernel Interfaces Manual — the ADMtek AN986 Pegasus USB Fast Ethernet driver, and yes bestie we're getting into it 💅✨

🌸 NAME 🌸

aue — ADMtek AN986 Pegasus USB Fast Ethernet driver

✨ SYNOPSIS ✨

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device uhci
device ohci
device usb
device miibus
device uether
device aue

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

if_aue_load="YES"

💖 DESCRIPTION 💖

The aue driver provides support for USB Fast Ethernet adapters based on the ADMtek AN986 Pegasus chipset.

The LinkSys USB10T adapters that contain the AN986 Pegasus chipset will operate at 100Base-TX and full-duplex.

The Pegasus contains a 10/100 Ethernet MAC with MII interface and is designed to work with both Ethernet and HomePNA transceivers. Although designed to interface with 100Mbps peripherals, the existing USB standard specifies a maximum transfer speed of 12Mbps. Users should therefore not expect to actually achieve 100Mbps speeds with these devices.

The Pegasus supports a 64-bit multicast hash table, single perfect filter entry for the station address and promiscuous mode. Packets are received and transmitted over separate USB bulk transfer endpoints.

The aue driver supports the following media types:

  • autoselect — Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the /etc/rc.conf file.
  • 10baseT/UTP — Set 10Mbps operation. The mediaopt option can also be used to enable full-duplex operation. Not specifying full duplex implies half-duplex mode.
  • 100baseTX — Set 100Mbps (Fast Ethernet) operation. The mediaopt option can also be used to enable full-duplex operation. Not specifying full duplex implies half-duplex mode.

The aue driver supports the following media options:

  • full-duplex — Force full duplex operation. The interface will operate in half duplex mode if this media option is not specified.

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

💀 DIAGNOSTICS 💀

  • aue%d: watchdog timeout — A packet was queued for transmission and a transmit command was issued, however the device failed to acknowledge the transmission before a timeout expired.
  • aue%d: no memory for rx list — The driver failed to allocate an mbuf for the receiver ring.
