Two flaws and a problem:
Flaw 1: The boot messages reveal what cards have been assigned what ethN number for some, but not all cards. E.g.,
# dmesg | grep eth eth0: 3c5x9 at 0x300, 10baseT port, address ..., IRQ 10. eth2: RealTek RTL8139 Fast Ethernet at 0xd080d000, ..., IRQ 9 eth2: Identified 8139 chip type 'RTL-8139A' eth3: i82596 ... #
What is eth1? This information seems not easily available.
I once gave a patch - can dig it up again if there is any interest. The kernel should report, preferably in a uniform way, ethN: Vendor Model, MAC address, ...
Flaw 2: Debugging output:
phy=0, phyx=24, mii_status=0xffff phy=1, phyx=0, mii_status=0xffff ... phy=24, phyx=23, mii_status=0xffff phy=25, phyx=25, mii_status=0xffff ... phy=31, phyx=31, mii_status=0xffff ***WARNING*** No MII transceivers found!
Problem: [The above two flaws apply to many kernel versions. However, today, upon booting 2.5.20 net connection failed.]
