[teammgrd] teamd cannot start when port channel was down before warm reboot

[stepanblyschak]

Steps to reproduce:

1. shutdown lag on peer
2. sudo warm-reboot on dut
3. observe continuous log about teamd fails to start because it cannot assign requested mac address

The issue seems to be introduced #1003.

The mac that teammgrd reads form saved PDU appears to be 00:00:00:00:00:00.

@shine4chen can you please check this issue?
Is it possible for you to reproduce it?

@pavel-shirshov Thank @stepanblyschak. We have reproduce it. It seems that when you shutdown lag on peer peer still tries to negotiate with dut , then saved pdu packet content is not suitable for restoring mac-address. We will add some pdu validation code to work it out.
