不然4 port網卡就掛了1 port.
改壞時，linux是無法載入也無法看到，透過一些指令去看，的確有看到卡，但沒用。
而舊方法是去改linux驅動，整死人⋯⋯
找到拯救方法之後，利用ethtool 備份的bin去寫回eeprom，結果問題多多。
最後是用一樣的拯救方法去備份另外 port的eeprom ，才順利改回來跟原始一模一樣的eeprom 。
英文不好，但為了讓改壞的人都能找到資料，就用破英文寫了

How to restore eeprom, I wrote above, but one important thing, binary file from ethtool command is smaller than real, cause some problems.
Here is my recommendation :
Boot to UEFI as I wrote, then follow these steps.
1)Eeupdate64e.efi -nic=X /DUMP
X is your card number.
Dump file will be MAC.EEP
MAC=mac address.
Backup this file.
Rollback is simple.
Just use UEFI.
Remember when rollback, -d must add to prevent write other MAC.
I350 4 port, just modify one port, make sure everything is fine, then do again with the other three ports.
