Re: [PATCH RFC] Providing a helper for PCS inband negotiation

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?
