Subject: [PATCH net 1/3] s390/qeth: don't erase configuration while probing

From: Julian Wiedmann <[email-masked]>
Date: Mon, 18 Mar 2019 16:40:54 +0100

The HW trap and VNICC configuration is exposed via sysfs, and may have
already been modified when qeth_l?_probe_device() attempts to initialize
them. So (1) initialize the VNICC values a little earlier, and (2) don't
bother about the HW trap mode, it was already initialized before.
