+Subject: [PATCH] net: sfp: add quirk for SFP-ONU-XGSPON module
+
+Add quirk for YV SFP+ONT-XGSPON module.
+
+This device uses pins 2 and 7 for UART communication, so disable
+TX_FAULT and LOS. Additionally as it is an embedded system in an
+SFP+ form factor provide it enough time to fully boot before we
+attempt to use it.
