func (*Ethereum) StartAutoDAG 

func (self *Ethereum) StartAutoDAG()

StartAutoDAG() spawns a go routine that checks the DAG every autoDAGcheckInterval by default that is 10 times per epoch in epoch n, if we past autoDAGepochHeight within-epoch blocks, it calls ethash.MakeDAG to pregenerate the DAG for the next epoch n+1 if it does not exist yet as well as remove the DAG for epoch n-1 the loop quits if autodagquit channel is closed, it can safely restart and stop any number of times. For any more sophisticated pattern of DAG generation, use CLI subcommand makedag

NewProtocolManager returns a new ethereum sub protocol manager. The Ethereum sub protocol manages peers capable with the ethereum network.

func (*ProtocolManager) BroadcastBlock 

func (pm *ProtocolManager) BroadcastBlock(block *types.Block, propagate bool)

BroadcastBlock will either propagate a block to a subset of it's peers, or will only announce it's availability (depending what's requested).
