Subject: runqemu: work with tap device names that end with a colon
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e46be72a8e5d064b4b46d5b0c37d67bbb2ccae55;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

runqemu: work with tap device names that end with a colon

On Fedora systems (and likely others), ifconfig returns interface
names that end with a colon. Make sure we strip the colon off the
tap device name before using it.

This fixes [YOCTO #3028]
