From 7302d61ac5741e3e724f47ee0906db6219a50c29 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Beh=C3=BAn?= Date: Fri, 22 Sep 2023 15:45:23 +0200 Subject: [PATCH] net: sfp: add support for Xicom's XC-SFP-T copper SFP module MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add support for Xicom's XC-SFP-T copper SFP module. This module requires a fixup so that the TX_FAULT signal is completely ignored via state_hw_mask.
