I reworked the commit description about the What and thought it was
enough. Do you need a cover letter to describe it more?

The Why is:
"
Configure the host port of the switch to match the host interface
settings. This is useful when the switch is directly connected to the
host MAC interface.
"
Thank you for reviewing the patch.
