Valid point. It deserves a better explanation.

 1. There is no change in the actual board revision.
 2. Moving from interrupt to polling works always, so it does not
    require any change on the board.
 3. On our board is possible to disconnect the interrupt just removing a
    jumper. The actual board revision stay the same. This is a new
    product, that is going to be generally available in a few days. We
    are going to ship boards with such jumper removed to
    solve the i.MX95 strap option issue on reset.
 4. Future board revisions might completely disconnect the ethernet
    interrupt, removing the actual connection from the schematics. Given
    we work in polling (after this patch is merged), this will be a
    transparent change that will not create any kind of software
    incompatibility.


Should I incorporate this detailed information in the commit message and
send a v2 or the current commit message is fine ?
