Pull request net-20260506.

net:
- phy: dp83867: default to 2ns delay if unspecified in device-tree
- nfs: fix buffer overflow in nfs_readlink_reply()
- cpsw: Add cpsw-switch DT binding support
- phy: add common PHY polarity properties support
- phy: adin: add support for the ADIN1200 phy
- macb: support for instances with less features
- phy: mscc: add support for the VSC8572

net-lwip:
- wget: correct diagnostic output
