Description Stephen Hemminger 2005-09-23 20:01:00 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.10) Gecko/20050909 Fedora/1.0.6-1.2.fc4 Firefox/1.0.6

Description of problem:
I am working on driver for SysKonnect dual-port Gigabit Ethernet card.
It is a single PCI device which supports two network devices.
Only the first port of the card shows up in the GUI config table.

Looking at strace output, it looks like the discovery process is looking
for PCI devices then probably assumes a 1:1 relationship, but in this
case it is possible to have a single PCI device with two network ports.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Get a dual-port Ethernet card (SK-9S22) and run sky2 or sk98lin driver
2. Run System Tools -> Network
3. Only one eth device is shown
  

Actual Results:  eth0 ....

Expected Results:  eth0 ....
eth1 ....

what does 
# ifconfig eth1 

say?

2. Run System Tools -> Network
3. Only one eth device is shown

Which dialog do you mean especially? You should be able to create the eth1
interface without any problem :)

Comment 5 Stephen Hemminger 2005-09-27 16:23:27 UTC 
Start system-config-network:

Initial screen should show three interfaces: (see attached)
  eth0 << Builtin in tg3 on this workstation
  eth1 << SK-9S22 port 0
  eth2 << SK-9S22 port 1

The problem (at least by looking at strace) is that the program is discovering
network devices by looking for hardware in /sys, and the SK-9S22 has two ports
for one piece of hardware.
Comment 6 Harald Hoyer 2005-09-28 07:00:27 UTC 
Err.. this screen only shows the configured devices. Try to "Add" a new
interface and see if "eth2" is in the list.
Comment 7 Stephen Hemminger 2005-09-28 16:26:26 UTC 
Yes, it does show up on the "New" button, that will work.
