Thanks for adding some comments in this series.

About this fix, would it be easier to understand if explaining
what is the bug first?

yes. I can be more specific here.
1. the dev->data->mtu was not getting updated earlier for the jumbo 
buffer config.
2. we don't expect to return error, if this config fails. A debug err 
log is ok.  DPAA1 - supports jumbo by default, enable/disable may give 
errors.
