Subject: [dpdk-dev] [PATCH v2] app/proc-info:fix port mask parse bug
Date: Mon, 5 Nov 2018 22:04:26 -0500 [thread overview]
Message-ID: <1541473466-27118-1-git-send-email-han.li1@zte.com.cn> (raw)
parse_portmask return type is int,but global variable
"enabled_port_mask" type is uint32_t.so in proc_info_parse_args
function,when parse_portmask return -1,"enabled_port_mask" will
get a huge value and "if (enabled_port_mask == 0)" will never happen.
