>Given this architecture, this driver cannot be used unless there is a switch driver as well. This driver is nearly ready to be merged. So what are your plans for the switch driver? Do you have a first version you can post? That will reassure us you do plan to release a switch driver, and not use a SDK in userspace.

Hi Andrew,
This GMAC is configured after the switch is boot-up and does not require a switch driver to work.
