>Description:
Kernel failed to initialize the following NIC
Genius III
K023B016 REV:A
Chip type RTL8139C, 14155S1, 116B
with
"rl0: unknown device ID: 0"
error message.
PCI Info: Vendor/Device ID 10EC/8129
Driver checks Device ID read from NIC's EPROM.
My card returns zeros when reading EPROM.
It also has internal PHY interface (like 8139)
