Subject: test/kni: check init result
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=381dfcf04717f92cfea68e53aac1979c098d35a4;p=dpdk.git

test/kni: check init result

Return value 'rte_kni_init' of a function is not checked. If
it fails, error handling (logging and return) should be done.

This patch fixed it.

Fixes: 0c6bc8ef70ba ("kni: memzone pool for alloc and release")
