VPP-540 : pbb tag rewrite details
Extended sw_interface_dump to provide 802.1ah (pbb) tag rewrite info if present. Extended log "l2-output" to provide raw data to display result of prospetive pbb tag rewrite. Tracing is moved after l2output_vtr to show these changes. Change-Id: I8b7cb865dc67ce21afab402cc086dac35f7c0f07 Signed-off-by: Pavel Kotucek <pkotucek@cisco.com>
