I don't think you understand the meaning of the Fixes: tag. It is
supposed to point to the first commit where the issue being fixed
started being visible. But git show 8abbffd27ced shows:

commit 8abbffd27cedd0f89f69e5ee2ff6841ea01511eb
Author: Arseniy Krasnov <AVKrasnov@xxxxxxxxxxxxxx>
Date:   Tue Jan 10 10:18:32 2023 +0000

    test/vsock: vsock_perf utility

    This adds utility to check vsock rx/tx performance.

    Usage as sender:
    ./vsock_perf --sender <cid> --port <port> --bytes <bytes to send>
    Usage as receiver:
    ./vsock_perf --port <port> --rcvlowat <SO_RCVLOWAT>

So:
1 - that has nothing to do with mv88e6xxx, so it cannot have introduced
    the issue here
2 - there is a mismatch between the blamed commit sha1sum and the blamed
    commit message. In fact, the blamed commit message is _your_ commit
    message, which is not correct.
