Description (partial)

Issue only happens when doing shut/no shut on PE side (ASR 9k). Shut needs to be for a few mins.

After this if we do port bounce on CE side (ASR 1001) then it recovers. In the testing we had to remove macsec from both sides and re-add it to recover links but normally bounce on CE side was enough.

I did notice tat when issue happens on the 9K MKA session is Init and on the ASR 1001 the session shows as secured.

We tried clearing MKA session on CE ASR 1001 but didn't recover. After this we have to remove macsec completely from both ends for it to re-esdtablish and then macsec can be added back.
