e1000: Identify SerDes adapters with LED blink
The generic LED on and off operations do not handle internal SerDes
media, leaving the led(4) device ineffective on my I210 fiber port.
Use the hardware blink operation for the on phase on internal SerDes.
The off phase restores the saved OEM LED configuration as before.
