>Description:
The ADMtek AN986 Pegasus USB Ethernet driver aue(4) currently has no support
for the HomePNA PHY interface for the PegasusII chipset. This means that
users who are using this USB device for HomePNA usage will not be able to
do so. The following patch addresses this lack of functionality by enabling
the HomePNA PHY with the 'ifconfig aueX media homepna' command, and enabling
the Ethernet PHY with the 'ifconfig aueX media auto' command. auto is also
synonymous with 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX. Reference
was made to the ADM8511 Datasheet at
http://www.admtek.com.tw/download/nic/adm8511/ADM8511_DSH_204.pdf.

Do note that upon USB attach, the HomePNA PHY is disabled and the
Ethernet PHY is enabled by default.

This PR contains a patch to /usr/src/sys/dev/usb/if_aue.c to enable the
HomePNA PHY as per the Description above.
>How-To-Repeat:
	Attach device to USB and configure for HomePNA
>Fix:

Apply the following patch to /usr/src/sys/dev/usb/if_aue.c
