From 9aac19b6c38f3813d6f22ad21764afff3a60651f Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 16 Aug 2020 09:32:18 +0100 Subject: net: phy: pass supported PHY interface types to phylib Pass the supported PHY interface types to phylib so that PHY drivers can select an appropriate host configuration mode for their interface according to the host capabilities. This is only done for SFP modules presently.
