Re: [gentoo-user] modules.conf - alias for eth devices - can't set the correct interface number

[Claudinei Matos]

Looking at /etc/udev/rules.d/ I'd found 70-persistent-net.rules with
the lines below:
# PCI Device: 0x10ec:0x8029 (ne2k-pci)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:c0:df:ea:d6:49",
NAME="eth1"

# PCI Device: 0x10b7:0x9200 (3c59x)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:04:75:c5:5c:ce",
NAME="eth2"

The interface with name eth1 match the mac address with the installed
one, but interface eth2 does not, probably 'cause it might be the old
card mac adress.

Well, now I know that in some way udev add these links automatically I
do thing that I can just change the mac address putting the right one,
letting the file appear like below:

   	 	 	 	 	 		
# PCI Device: (via-rhine)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:50:8D:84:A8:4F",
NAME="eth0"

# PCI Device: 0x10ec:0x8029 (ne2k-pci)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:C0:DF:EA:D6:49",
NAME="eth1"

# PCI Device: 0x10b7:0x9200 (3c59x)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:50:04:6E:9C:AB",
NAME="eth2"


Well, that's OK, it do solve my problem but isn't it supposed to be an
automatically process? Isn't it an UDEV or Gentoo task to deal with?
