From be6ec5b7026620b931e0fa9287d24ad2cd2ab9b6 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Wed, 26 Jan 2022 10:25:55 +0000 Subject: net: xpcs: add support for retrieving supported interface modes Add a function to the xpcs driver to retrieve the supported PHY interface modes, which can be used by drivers to fill in phylink's supported_interfaces mask. We validate the interface bit index to ensure that it fits within the bitmap as xpcs lists PHY_INTERFACE_MODE_MAX in an entry.
