SRU justification:

[Impact]
igc driver can not connect to network after re-plugin thunderbolt dock when
MAC passthrough enabled in BIOS.

[Fix]
Wait for the MAC copy of BIOS when enabled MAC passthrough.
Intel engineer wants a different solution and promise to discuss with firmware engineer.
Due to the schedule, made this as a short term solution to fix the issue, and wait for the other
fix from Intel.

[Test]
Verified on hardware, after hotplug the thunderbolt cable,
Ethernet works fine.

[Where problems could occur]
It may break the igc driver.
