Subject: [RFC PATCH net-next 0/5] net: macb: Add versal2 10GBE device support
Date: Wed, 9 Oct 2024 11:09:41 +0530	[thread overview]
Message-ID: <20241009053946.3198805-1-vineeth.karumanchi@amd.com> (raw)

10GBE IP is a HighSpeed mac that supports 1G, 2.5G, 5G, and 10G speeds
and has two PCS. It has USX PCS for higher speed and SGMII PCS for
lower speed transmission.

Auto-neg is disabled for this IP in versal2 device, hence "fixed-link"
at the specified speed is used. It is an expansion of the fixed-line speed
at 10G currently being implemented. These modifications are tested using
a HW board configuration without a PHY with QSFP.

The IP contains MDIO lines, and the goal is to use auto-neg in the PHY
and set the agreed-upon speed in the MAC. These adjustments will be made
in the following phase after the extra hardware is available.

Vineeth Karumanchi (5):
  dt-bindings: net: macb: Add support for versal2 10gbe device
  net: macb: Add versal2 10GBE device support
  net: macb: Update USX_CONTROL reg's bitfields and constants.
  net: macb: Configure High Speed Mac for given speed.
  net: macb: Get speed and link status runtime.
