I read in the e1000e README about issues with the EEPROM having APRM
enabled in some older 82573x NICs. These are the NICs I had so I ran
the script mentioned in the README (and also confirmed by hand with
ethtool -e ethx) and see that the APRM is not enabled at least in the
0x1e location the README refers to:

[root@dd43 ~]# lspci

[root@dd43 ~]# ./fixeep-82573-dspd.sh eth1
eth1: is a "82573V Gigabit Ethernet Controller"
This fixup is applicable to your hardware
Your eeprom is up to date, no changes were made

[root@dd43 ~]# ./fixeep-82573-dspd.sh eth0
eth0: is a "82573L Gigabit Ethernet Controller"
This fixup is applicable to your hardware
