There are several issues here:

1. Submitting to netdev needs either [PATCH net] or [PATCH net-next]
   to indicate which tree is being targetted. As this isn't a fix,
   net-next is appropriate, but I would also suggest that it is too
   late in the cycle as v6.7 is due out today.

2. How does the module switch between 1000base-X and 2500base-X?
   What happens if the module wants to use 2500base-X but the host
   doesn't support it? Please include these details in the commit
   message.

3. While I know the Turris Rollball entries are out of order, please
   try to keep the list alphabetically sorted, first by vendor string
   and then part string.

Thanks.
