Hi Russell,

Ok, that's a typo.

Copy your big comment here:
int phy_addr;
/* MAC ----- optional PCS ----- SerDes ----- optional PHY ----- Media
* ^ ^
* mac_interface phy_interface
*
* mac_interface is the MAC-side interface, which may be the same
* as phy_interface if there is no intervening PCS. If there is a
* PCS, then mac_interface describes the interface mode between the
* MAC and PCS, and phy_interface describes the interface mode
* between the PCS and PHY.
*/
phy_interface_t mac_interface;
/* phy_interface is the PHY-side interface - the interface used by
* an attached PHY.
*/
Our hardware engineer said we don't support pcs, and if I understand
your comment correctly, our mac_interface and phy_interface should
be the same, right?
Thanks,
Yanteng
