Subject: [PATCH net 0/3] net: fix optical SFP failures
Date: Sun, 31 Aug 2025 18:34:17 +0100	[thread overview]
Message-ID: <aLSHmddAqiCISeK3@shell.armlinux.org.uk> (raw)

Hi,

A regression was reported back in April concerning pcs-lynx and 10G
optical SFPs. This patch series addresses that regression, and likely
similar unreported regressions.

These patches:
- Add phy_interface_weight() which will be used in the solution.
- Split out the code that determines the inband "type" for an
  interface mode.
- Clear the Autoneg bit in the advertising mask, or the Autoneg bit
  in the support mask and the entire advertising mask if the selected
  interface mode has no inband capabilties.

Tested with the mvpp2 patch posted earlier today.
