[dpdk-dev] [PATCH] bond: disabling broadcast mode when dpdk is built without RTE_MBUF_REFCNT

[Declan Doherty <declan.doherty@intel.com>]

Link bonding broadcast mode requires refcnt parameter in the mbuf struct to 
allow efficient transmission of duplicated mbufs on slave ports. 

This patch disables broadcast mode when the complication option RTE_MBUF_REFCNT
is disabled to allow clean building of the bonding library
