stable inclusion from stable-v6.6.8 commit 885faf3c7e5f53561c34104d140f2e321ea305a6 bugzilla: https://gitee.com/openeuler/kernel/issues/I99K53
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 02e7d139e5e24abb5fde91934fc9dc0344ac1926 upstream.
Change the key that we send from IB driver to EN driver regarding the MPV device affiliation, since at that stage the IB device is not yet initialized, so its index would be zero for different IB devices and cause wrong associations between unrelated master and slave devices.
Instead use a unique value from inside the core device which is already initialized at this stage.
