Subject: [RFC PATCH v3 net-next 0/6] Let phylink manage in-band AN for the PHY
Date: Wed, 22 Sep 2021 21:14:40 +0300 [thread overview]
Message-ID: <20210922181446.2677089-1-vladimir.oltean@nxp.com> (raw)
This small series creates a configuration knob for PHY drivers which use
serial MII-side interfaces and support clause 37 in-band auto-negotiation
there. With this knob, phylink can control both the MAC side and the PHY
side, and keep them in sync, which is needed for a functional link. This
fixes the VSC8514 QSGMII PHY on the NXP T1040RDB and LS1028ARDB which is
described in the device tree as having in-band autoneg enabled, but
sometimes it has and sometimes not, depending on boot loader version.
Changes in v2:
Incorporated feedback from Russell, which was to consider PHYs on SFP
modules too, and unify phylink's detection of PHYs with broken in-band
autoneg with the newly introduced PHY driver methods.

Changes in v3:
Added patch for the Atheros PHY family.
Vladimir Oltean (6):
net: phylink: pass the phy argument to phylink_sfp_config
net: phylink: introduce a generic method for querying PHY in-band
autoneg capability
net: phy: bcm84881: move the in-band capability check where it belongs
net: phylink: explicitly configure in-band autoneg for PHYs that
support it
net: phy: mscc: configure in-band auto-negotiation for VSC8514
net: phy: at803x: configure in-band auto-negotiation for AR8031/AR8033
