Member Data Documentation

bufLength

unsigned gem5::EthPacketData::bufLength

Total size of the allocated data buffer.

data

uint8_t* gem5::EthPacketData::data

Pointer to packet data will be deleted.

Referenced by serialize(), unserialize(), and ~EthPacketData().

length

unsigned gem5::EthPacketData::length

Amount of space occupied by the payload in the data buffer.

Definition at line 65 of file etherpkt.hh.

Referenced by serialize(), and unserialize().

simLength

unsigned gem5::EthPacketData::simLength

Effective length, used for modeling timing in the simulator.

This could be different from length if the packets are assumed to use a tightly packed or compressed format, but it's not worth the performance/complexity hit to perform that packing or compression in the simulation.
