2. XLGMII.. Looking at the XPCS driver, it's unclear whether Clause 73 AN gets used for this. A quick scan of IEEE 802.3 suggests that XLGMII doesn't have any support for any inband signalling, and it's just an intermediary protocol between the MAC (more specifically the RS, but for the purposes of this I'll just refer to MAC) and the attached PCS, and any autonegotiation happens after the XLGMII link.
So isn't XLGMII then a generic PHY thing, not a phylink thing? Or am i not correctly understanding how drivers/phy/marvell/phy-*-comphy.c and drivers/phy/microchip/*_serdev.c fit into the overall picture?
