Subject: app/testpmd: fix allocation check in TM config
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9e70fce2e1cfb5f5061272b3051c5a95cf0a1ef5;p=dpdk.git

app/testpmd: fix allocation check in TM config

Calloc() function might returns NULL due to insufficient space. Therefore,
check for handling memory allocation failure is added.

Coverity issue: 257030
Fixes: 5b590fbe09b6 ("app/testpmd: add traffic management forwarding mode")
