ISSUE: 2nd Ethernet interface on Netra t1 not recognised.
> SYNOPSIS: Early shipments of Netra t1 Servers may have been shipped with
> the second ethernet port disabled.
>
> PROBLEM DESCRIPTION:
>
> By manufacturing default, the Sun Netra t1 Server OBP env parameter
> pcib-probe-list was set to 1,2 which means that only devices 1 and 2
> on the bus are probed and enabled, thus, only the ebus and the first
> ethernet device are enabled. The second ethernet port device 3, be-
> comes disabled by default.
>
> The above mentioned problem can be identified on a Sun Netra t1 Server
> from the OK prompt, by typing 'show-devs', if the following error is
> displayed:
>
> Unable to find `/pci at 1f,0/pci at 1,1/network at 3,1'
>
> The Netra t1 Server does not recognize the second ethernet device.
>
> During the manufacturing and testing process the pcib-probe-list is
> set to 1,2,3 thus, the second ethernet device is enabled. Then at
> the end of the system test, a script performs a 'set-defaults' on
> the obp parameters, which returns the second ethernet device to the
> disabled state. As a result, hme1 is not probed and the second ether-
> net port is therefore not added to the device tree.
>
> CORRECTIVE ACTION:
>
> 1. Log in as/su to root
>
> 2. Type the following three lines:
>
> eeprom pcib-probe-list=1,2,3
> eeprom output-device=ttya
> eeprom input-device=ttya
>
> 3. Reboot
