Subject: selftests: rtnetlink: skip ipsec offload tests if netdevsim isn't present
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3099c59db0f2d6b85389af5ac652569bac3f1ee8;p=openwrt%2Fstaging%2Fblogic.git

selftests: rtnetlink: skip ipsec offload tests if netdevsim isn't present

running the script on systems without netdevsim now prints:

SKIP: ipsec_offload can't load netdevsim

instead of error message & failed status.
