From cb8bac12ec92ec469ecfe0967429bf9032f835c1 Mon Sep 17 00:00:00 2001 From: Ron Mercer Date: Mon, 26 Feb 2007 11:06:36 -0800 Subject: [PATCH] qla3xxx: Remove API to change MTU. This network device driver shares the same hardware as the qla4xxx iSCSI driver. Changing the MTU via the device interface will cause qla4xxx to crash as there is no way to make notification. Users wishing to change the MTU must do so using an iSCSI utility such as Qlogic SanSurfer. This forces the user to unload/reload this network device driver after the MTU value has been changed in flash.
