[dpdk-dev] [PATCH]net/bonding: add DEFAULTED state in rx_machine in 802.3ad bonding implementation

[lidejun]

Hi All:
This patch fixes a issue when DPDK 802.3ad bonding rx_machine enters EXPIRED 
state, but the opposite SWITCH lacp ignores distributing and collecting bit, so 
the SWITCH still sends packets to DPDK and all these packets are dropped.
