SubjectRe: [PATCH net-next v3] net: dsa: make "label" property optional for dsa2
From: Vivien Didelot <>

> In the new DTS bindings for DSA (dsa2), the "ethernet" and "link"

> This allows to save DTS files from subjective net device names.
> If one wants to rename an interface, udev rules can be used as usual.
> Of course the current behavior is unchanged, and the optional "label"
> property for user ports has precedence over the enumerated name.
