Subject: YANG Versioning Question - iana-if-type Update

Dear YANG Doctors,

I need guidance on classifying a change to the iana-if-type module.

Change Description:
The Interface Types registry has updated the description for
interface type 6 (ethernet) to clarify that it includes both
10BASE-T and 100BASE-T variants.

Proposed YANG Change:
Update the description statement for the "ethernet" enum to
include the clarification.

Question:
Should this be classified as Editorial (PATCH increment) since
it's clarifying existing behavior, or as BC (MINOR increment)
because it's adding new information?

The old description said: "Ethernet interface"
The new description says: "Ethernet interface, including
10BASE-T and 100BASE-T variants"

Current module version: 1.5.0
Proposed version: 1.5.1 (if Editorial) or 1.6.0 (if BC)

Thank you for your guidance.
