Symptom
After upgrading FTDv on Azure from 6.6 to FTDv 6.7, the GigabitEthernet interfaces can only be set to auto and speed it reports is 10Gbps.

MAC address 000d.3a6d.0fbb, MTU 1500
Conditions
FTDv on Azure running version 6.7
Workaround
There is no workaround.
To eliminate the policy deployment failure due to this issue, configure speed auto on the FMC.
On FDM, it no longer allows speed setting other than auto.
