What does 'dmesg | grep -e 01:0a -e eth' report?

Have you read /usr/src/linux/Documentation/networking/e1000.txt ?

ifconfig -a
Maybe it's a different name.  You can, of course use custom udev rules to 
name 
it however you wish, but features like etherenet over USB and ethernet over 
firewire can cause your "only" NIC to show up with a different name.

How can I rename eth3 to eth0?
Or if I use eth3,what do I need to do to fix it?
Cause after I changed eth0 to eth3 in cond.d/net and added eth3 to
rc-update,when I boot up my machine,new error occur:

Bringing up eth3
     default
     No load modules provide "default" (default-start)
Error:cannot start netmount as net.eth3.could not start

Thank you!

Modify the file /etc/udev/rules.d/70-persistent-net.rules to suit your needs.

I doubt that this is related to the fact that the interface
is called "eth3" instead of "eth0". On my machine, I also
have no "eth0", just a "tg3".

What do you have in /etc/conf.d/net?

When I use eth3,my conf.d/net is:

config_eth3=( "192.168.83.123 netmask 255.255.255.0 brd 192.168.83.255" )
config_eth3=( "default gw 192.168.83.254" )


Now every time in gentoo,I use the script to start the eth3:

ifconfig eth3 192.168.83.123 broadcast 192.168.83.255 netmask 255.255.255.0 up
route add default gw 192.168.83.254

Try changing that to:
config_eth3=( "192.168.83.123 netmask 255.255.255.0 brd 192.168.83.255" )
routes_eth3=( "default gw 192.168.83.254" )

That should solve your problem, for comparison, this is what I have in my
/etc/conf.d/net:
config_dmz2=( "10.1.4.11 netmask 255.255.255.0 broadcast 10.1.4.255" )
routes_dmz2=( "default gw 10.1.4.1" )

Thank you! I think I made a silly mistake!
