Subject: test: check flow classifier creation
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=705b04af1c100c464b6d9238408e84cfeffc489c;p=dpdk.git

test: check flow classifier creation

'cls->cls' will be NULL if flow classifier create has failed,
then segmentation fault will occur if the variable is used.

This patch fixed it.

Fixes: 9c9befea4f57 ("test: add flow classify unit tests")
