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.
