Subject: s390/qeth: don't erase configuration while probing
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=12b409dd32dffad6d800774e2d250adaaaa1fdcd;p=openwrt%2Fstaging%2Fblogic.git

s390/qeth: don't erase configuration while probing

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.
