[in]	dataLen	Size of the data in bytes
[in]	packet	A pointer to the Packet instance where layer will be stored in

◆ Sll2Layer() [2/2]

pcpp::Sll2Layer::Sll2Layer	(	uint32_t	interfaceIndex,
		uint16_t	ARPHRDType,
		uint8_t	packetType

[in]	dataLen	The length of the byte stream

Returns: True if the data is valid and can represent an IEEE 802.3 Eth packet

◆ parseNextLayer()

void pcpp::Sll2Layer::parseNextLayer ( )

overridevirtual

Currently identifies the following next layers: IPv4Layer, IPv6Layer, ArpLayer, VlanLayer, PPPoESessionLayer, PPPoEDiscoveryLayer, MplsLayer. Otherwise sets PayloadLayer

Implements pcpp::Layer.

◆ setArphrdType()

void pcpp::Sll2Layer::setArphrdType ( uint16_t arphrdType )
