SOLVED: ADMtek USB To LAN Converter and HomePNA

[Dinesh Nair]

people,

the following patch solves this problem. according to the ADM8511
datasheet, a couple of registers need to be set with specific values to
enable the HomePNA PHY on the device. the current aue(4) driver does not
do this, and thus by default the device will only enable the Ethernet PHY.
you'd need to rebuild kernel or just kldunload/kldload if using the
if_aue.ko module.

 hey,

 i have one of the above. it's a usb device which connects to a HomePNA

 the HomePNA connection.

 my problem is i am unable to utilize this device to connect to the HomePNA
 network. upon plugging it in, the console says:

 miibus1: MII bus on aue0
 pnaphy0: Am79c978 HomePNA PHY on miibus1

 ifconfig aue0 response is:
 aue0: flags=8802BROADCAST,SIMPLEX,MULTICAST mtu 1500
 ether 00:08:54:d0:5d:2e
 media: Ethernet homePNA (none)

 i run 'ifconfig aue0 10.1.105.26 netmask 0x media homepna' and the
 device then gets to the following:

 aue0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500
 inet 10.1.105.26 netmask 0x broadcast 10.1.255.255
 ether 00:08:54:d0:5d:2e
 media: Ethernet homePNA
 status: active

 however, i am unable to ping any ip address other than the interface's
 address. obviously, no firewalls (ipfw/ipchains/ipf) are being run and
 this is on FreeBSD 4.9-STABLE built as of a couple of weeks back.

 i've played around with disabling the ethernet PHY on the device with the
 following diff to /usr/src/sys/dev/usb/if_aue.c:

 but to no avail. i've discovered that the ethernet PHY is phy==1, while
 the two RJ11 PHYs are 2 and 3.

 the ethernet PHY works fine and dandy, and i am able to connect it to my
 local switch fine. however, i need to use it for a HomePNA application,
 and thus need to HomePNA portion of this to work.

 any ideas from anyone who's tried something like this before with some
 measure of success ? any media types or mediaopts i should be passing to
 ifconfig ?

 this setup is used by a broadband provider in kuala lumpur, malaysia and
 to date this has been the one barrier which prevents freebsd users from
 utilizing their service.

use the following patch instead of earlier one. earlier patch hardcoded
use of HomePNA PHY and disabled Ethernet PHY. this patch corrects this
behaviour and allows switching between either PHY thru use of the ifconfig
command. this means that the USB dongle can either be used as an Ethernet
device (connect to switch/hub) or as a HomePNA access device, but not both
simultaneously.

ifconfig aue0 media homepna # activates HomePNA PHY/RJ11
ifconfig aue0 media auto # activates Ethernet PHY/RJ45

using auto as media type is synonymous with the following media types:

10baseT 10baseT-FDX 100baseTX 100baseTX-FDX

much apologies for not checking things correctly before submitting the
patch.

patch follows:
