Subject: [PATCH net-next v11 00/13] Introduce PHY listing and link_topology tracking
Date: Thu, 4 Apr 2024 11:29:50 +0200 [thread overview]
Message-ID: <20240404093004.2552221-1-maxime.chevallier@bootlin.com> (raw)
Hello everyone,
This is V11 for the link topology addition, allowing to track all PHYs
that are linked to netdevices.
This V11 addresses the various netlink-related issues that were raised
by Jakub, and fixes some typos in the documentation.
As a remainder, here's what the PHY listings would look like :
- eth0 has a 88x3310 acting as media converter, and an SFP module with
an embedded 88e1111 PHY
- eth2 has a 88e1510 PHY
# ethtool --show-phys *
PHY for eth0:
PHY index: 1
Driver name: mv88x3310
PHY device name: f212a600.mdio-mii:00
Downstream SFP bus name: sfp-eth0
PHY id: 0
Upstream type: MAC
PHY for eth0:
PHY index: 2
Driver name: Marvell 88E1111
PHY device name: i2c:sfp-eth0:16
PHY id: 21040322
Upstream type: PHY
Upstream PHY index: 1
Upstream SFP name: sfp-eth0
PHY for eth2:
PHY index: 1
Driver name: Marvell 88E1510
PHY device name: f212a200.mdio-mii:00
PHY id: 21040593
Upstream type: MAC
