Re: [dpdk-dev] [PATCH v4 4/8] app/proc-info: add more info to show_ports

["Hemant Agrawal (OSS)" <hemant.agrawal@oss.nxp.com>]

Will you please also print queue mempool info
+                               printf("\t  -- mempool name: %s\n",
+                                       (queue_info.mp == NULL) ?
+                                       "NULL" : queue_info.mp->name);

Subject: [PATCH v4 4/8] app/proc-info: add more info to show_ports

Revise the display of port information to include more data and be more human friendly.

  * Display units for port speed, and decode link fields.
  * Show driver and device information
  * Show MAC address
  * Show flow control information
  * Combine lines if possible
  * Show all multicast mode
