Please don't indent commit messages unnecessarily.

Also, good to know what this module *requires* AN with 2500base-X.

However, what mode does this module normally come up in, and does
it reflect the operating mode in the module EEPROM?

If we accept this patch, and the modules normally come up at 1000base-X
we will try to use 2500base-X and the link won't come up. So it's
important to clarify this point.

Thanks.
