From 29cd215aaf6c2050c43e4de03aee436c16f90b96 Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 21 Nov 2019 17:27:14 +0000 Subject: [PATCH 643/660] net: sfp: remove incomplete 100BASE-FX and 100BASE-LX support The 100BASE-FX and 100BASE-LX support assumes a PHY is present; this is probably an incorrect assumption. In any case, sfp_parse_support() will fail such a module. Let's stop pretending we support these modules.
