Subject: pdump: fix error code check when creating/canceling pthread
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8eff9b86aa1b73d0c2b225cb670bf033f32fbb43;p=dpdk.git

pdump: fix error code check when creating/canceling pthread

On error, pthread_create() returns a positive number (an errno)
but does not set the errno variable.

Fixes: 278f945402c5 ("pdump: add new library for packet capture")
