Note that this PDU contains the 802.3 LLC structure + SNAP frame. So far only unnumbered information structure is supported.
Tins::SNAP::SNAP | ( | const uint8_t * | buffer, |
uint32_t | total_sz | ||
) |
Constructs a SNAP object from a buffer and adds all identifiable PDUs found in the buffer as children of this one.
If the next PDU is not recognized, then a RawPDU is used.
If there is not enough size for a SNAP header in the buffer, a malformed_packet exception is thrown.
buffer | The buffer from which this PDU will be constructed. |
total_sz | The total size of the buffer. |
