[dpdk-dev] [PATCH 4/8] bond: queue stats mapping

[Tomasz Kulasek <tomaszx.kulasek@intel.com>]

Queue stats mapping is used in example application. This patch adds propagation
of mapping over the slaves, and fills bonding port's stats with a sum of
corresponding values taken from bonded slaves, when stats are requested for
bonding port.
