Subject: net/bonding: add LACP info dump
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit b00119fc03dc585213236ea7f550662befa68fbe ]

This patch adds dump lacp info in eth_dev_priv_dump ops.

The extra dump output is similar to testpmd command
"show bonding lacp info [port]".
