They are causing issue.

It would be nice to document the issues, in case users encounter them, 
they will know this patch is fixing it. Can you please send details?

1.  Portal was incorrectly initialized. PI was getting assigned to CI 
incorrectly. This avoided few un-explained issues when using event mode.

2. This provided minor performance improvement

btw, is the understanding correct that this patch is fixing issues 
only seen with qbman 5.0?

yes.

This fixes few random packet hang issues in event mode.
