Bug description:
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.
