Subject: s390/qeth: don't re-start read cmd when IDX has terminated
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3a5bad64db30a07459eb2f15ce6a4b995474350d;p=openwrt%2Fstaging%2Fblogic.git

s390/qeth: don't re-start read cmd when IDX has terminated

Once the IDX connection is down, there's no point in trying to issue
more IOs.
