- Subject: [PATCH] net: phy: define PSGMII PHY interface mode
- The PSGMII interface is similar to QSGMII. The main difference
- is that the PSGMII interface combines five SGMII lines into a
- single link while in QSGMII only four lines are combined.
- Similarly to the QSGMII, this interface mode might also needs
- special handling within the MAC driver.
- Add definitions for the PHY layer to allow to express this type
- of connection between the MAC and PHY.
