There are two bonding modes equivalent to static link aggregation, which use different algorithms for determining which slave to send on next. Round-robin and balance-xor will both work (modes 0 and 2). Balance-xor bases its choice of slave for sending on the xor of the source and destination MAC addresses, while round-robin just cycles through the available slaves. Chances are you probably want balance-xor.
