Description of problem:
Some network drivers can't tell if network cable is connected, when
such card/driver is used, initscripts assume "link is down" and don't
bring interface up.
This bug has hit particulary hard on users using HomePNA (1Mbit/s
ethernet over phonelines) style broadband connections and DHCP.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Fedora Core 1
2. Try to connect to network using HomePNA
Actual Results: Computer nevers attempts to discover IP using DHCP,
instead error message " failed; no link present. Check cable?" is shown.
Expected Results: Networking works fine after commenting out
check_link_down check on lines 274-278 in
Most HomePNA PCI cards seem to use AMD pcnet32 driver. It might be
driver issue or maybe it is impossible to detect link beat on such media.
Something (mii-tool or ethtool) prints some messages during network
start indicating network link existence cannot be detected on this
interface/hardware. In that case it should be assumed that cable is
connected and continue as usual.
It's a driver/physical issue. The driver claims that the link is down;
if it just said that the operation wasn't supported, we wouldn't
assume that it is down.
