Many thanks.

Here is the output:

srw1:~# ./fixeep eth1
eth1: is a "82573L Gigabit Ethernet Controller"
This fixup is applicable to your hardware
Your eeprom is up to date, no changes were made
srw1:~# ./fixeep eth0
eth0: is a "82573E Gigabit Ethernet Controller"
This fixup is applicable to your hardware
executing command: ethtool -E eth0 magic 0x108c8086 offset 0x1e value 0xdf

If will be any problem I will report it.
If I understand correctly, it is fixed forever.  Or must I run it after every
reboot ?
