ueagle
Analog Devices Eagle ADSL modems

ueagle* at uhub? port ?

The ueagle driver provides support for USB ADSL modems based on the Analog Devices Eagle chipset (revision I, II and III).
The ueagle driver can only manage a single ATM AAL5 virtual circuit. The segmentation and reassembly (SAR) of ATM cells is done by software.
To achieve high rate downstream transfer with fast ADSL connections, the ueagle driver uses USB isochronous pipes instead of standard bulk pipes.
To establish a permanent virtual circuit (PVC) with a peer, ueagle must be configured using the route(8) command. A typical invocation is:
# route add -iface <Peer IP> -link if:encap.vpi.vci_hi.vci_lo
The arguments to “-link” are as follows:
if
Interface name. For example, “ueagle0”.
encap
Type of encapsulation to use. Possible types are:
AAL5 VCMUX
Use hex value 0x1.
AAL5 LLC/SNAP
Use hex value 0x3.
vpi
See ISP's recommended setting for this. All values specified in hex.
vci_hi
 
vci_lo
See ISP's recommended setting for this. All values specified in hex. The VCI is specified as high_order_byte.low_order_byte. For example, a VCI of 35 would be specified as “0.23”.

The adapter needs some firmware files, which are loaded on demand:
/etc/firmware/ueagleI
 
/etc/firmware/ueagleII
 
/etc/firmware/ueagleIII
 
/etc/firmware/ueagle-dsp
 
These firmware files are not free because Analog Devices refuses to grant distribution rights.
A prepackaged version of the firmware, designed to be used with pkg_add(1), can be found at:
http://firmware.openbsd.org/firmware/ueagle-firmware-1.0p0.tgz

To establish a PVC (vpi=8, vci=35, vcmux) with host 192.168.1.2:
# route add -iface 192.168.1.2 -link ueagle0:1.8.0.23
To establish a PVC (vpi=0, vci=6, llc/snap) with host 192.168.1.3:
# route add -iface 192.168.1.3 -link ueagle0:3.0.0.6

The ueagle driver first appeared in OpenBSD 3.8.

The ueagle driver was written by Damien Bergamini ⟨damien@openbsd.org⟩.

The ueagle driver only supports ADSL over POTS. ADSL over ISDN is not supported. G.Lite modulation (aka splitterless) has never been tested and probably won't work.
