From: Alexandra Winter Date: Mon, 23 Dec 2019 14:03:23 +0000 (+0100) Subject: s390/qeth: fix false reporting of VNIC CHAR config failure X-Git-Tag: v5.5-rc5~20^2~23^2~3 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=68c57bfd52836e31bff33e5e1fc64029749d2c35;p=users%2Fjedix%2Flinux-maple.git s390/qeth: fix false reporting of VNIC CHAR config failure Symptom: Error message "Configuring the VNIC characteristics failed" in dmesg whenever an OSA interface on z15 is set online. The VNIC characteristics get re-programmed when setting a L2 device online. This follows the selected 'wanted' characteristics - with the exception that the INVISIBLE characteristic unconditionally gets switched off. For devices that don't support INVISIBLE (ie. OSA), the resulting IO failure raises a noisy error message ("Configuring the VNIC characteristics failed"). For IQD, INVISIBLE is off by default anyways. So don't unnecessarily special-case the INVISIBLE characteristic, and thereby suppress the misleading error message on OSA devices.
