Package: linux-image-2.6.26-2-ixp4xx
Version: 2.6.26-19lenny2
Severity: normal
I've been experimenting with a Pegasus-chipset USB ethernet adapter on
an NSLU2 unit. If the adapter is connected prior to system boot, although it
will be recognized by the kernel and udev, it starts out with a MAC address of
00:00:00:00:00:00. Since Debian's networking system doesn't customarily set
MAC addresses (and wouldn't really know the right one anyway if the device
didn't express one), this leaves the device unusable without manual
intervention. It can't be ifupped without setting the MAC; once that's done,
the device functions normally.
This behavior does not manifest if the adapter is hot-plugged; if the host
is booted first and the device plugged in hot, it does exhibit a nonzeroed MAC
and works without intervention.
I did my testing with the NSLU2's onboard ethernet also enabled, there being
no other good way to control the unit.
Some pertinent hardware info:
# udevadm info -a -p /sys/class/net/eth1
Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
