[dpdk-dev] [PATCH v6 4/9] app/procinfo: add support for show port

[Vipin Varghese <vipin.varghese@intel.com>]

Function show_port is used for displaying the port PMD information under
under primary process. The information shows basic, per queue and security.

Signed-off-by: Vipin Varghese <vipin.varghese@intel.com>

V5:
 - convert 100 to MAX_STRING_LEN - Reshma Pattan
 - RSS made for port - Reshma Pattan
 - update bdr_str to static - Stephen Hemminger
 - remove memset for link, dev_info, queue, stats - Stephen Hemminger

V3:
 - fix meson build - Reshma Pattan
 - change 100 to MAX_STRING_LEN - Reshma Pattan
 - memset to struct elements - Reshma Pattan
 - printf tab space - Reshma Pattan
 - remove 'drop packet information' - Vipin Varghese

V2:
 - redefine code format - Vipin Varghese
