[PATCH 0/1][SRU][H/OEM-5.13/OEM-5.14/U] UBUNTU: SAUCE: Fix invalid MAC address after hotplug tbt dock

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/1942999

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.
