[PATCH] [PATCH v2 net-next] bonding: Convert multiple netdev_info messages to netdev_dbg

Michael J Dilmore
2017-06-20T22:08:01Z

The bond_options.c file contains several netdev_info messages that clutter kernel output. This patch changes all netdev_info messages
to netdev_dbg and adds a netdev debug for the packets per slave parameter.
