[dpdk-dev] [PATCH] net/bonding:fix balance-xor link down stack overflow

[jilei]

When slave link down, deactivate_slave will internals->active_slaves
and internals->active_slave_count.Active_slave in bond_ethdev_rx_burst
may out of range in internals->active_slaves.It will get bond's port_id
cause stack overflow
