From c07c6e8eb4b38bae921f9e2f108d1e7f8e14226e Mon Sep 17 00:00:00 2001 From: Marek Behún Date: Thu, 28 Oct 2021 18:00:14 +0100 Subject: net: dsa: populate supported_interfaces member MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a new DSA switch operation, phylink_get_interfaces, which should fill in which PHY_INTERFACE_MODE_* are supported by given port. Use this before phylink_create() to fill phylinks supported_interfaces member, allowing phylink to determine which PHY_INTERFACE_MODEs are supported.
