fragmentPacket()

std::tuple< bool, std::vector< lp::Packet > > nfd::face::LpFragmenter::fragmentPacket	(	const lp::Packet &	packet,
		size_t	mtu
	)

fragments a network-layer packet into link-layer packets

Parameters

packet	an LpPacket that contains a network-layer packet; must have Fragment field, must not have FragIndex and FragCount fields
mtu	maximum allowable LpPacket size after fragmentation and sequence number assignment

Returns

whether fragmentation succeeded, fragmented packets without sequence number
