Subject: app/testpmd: avoid process ID out of range
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5388be6eaea7ceaa5a922ea6a8b4dada846aaeea;p=dpdk.git

app/testpmd: avoid process ID out of range

The 'proc_id' should be less than 'num_procs', if not, exit the testpmd
and show the error message.

Fixes: a550baf24af9 ("app/testpmd: support multi-process")
