From ecd57017429e3f5c07928fb7ca01c8c67066ed2f Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Tue, 16 Sep 2025 22:46:36 +0100 Subject: [PATCH] net: phy: add phy_interface_copy() [ Upstream commit a571f08d3db215dd6ec294d8faac8cc4184bc4e4 ] Add a helper for copying PHY interface bitmasks. This will be used by the SFP bus code, which will then be moved to phylink in the subsequent patches.
