const uint8_t *data, size_t len,

throw(InvalidPacket) | ipv6_checksum_verify |
#include <packet.hh>
Verify the checksum of an IPv6 PDU, throw an exception if the checksum doesn't match.
In IPv6 the payload is not checksummed it is up to the protocol to checksum its own payload. The checksum includes a pseduo header that is described in RFC 2460 section 8.1
Parameters:
| src | Source address of packet. |
| dst | Destination address of packet. |
| data | pointer to payload. |
| len | length of payload. |
| checksum_offset | offset of checksum in the payload. |
| protocol | protocol number. |

size_t checksum_offset, uint8_t protocol)
throw(InvalidPacket) | ipv6_checksum_apply |
#include <packet.hh>
Compute the IPv6 checksum and apply it to the packet provided. If the checksum_offset is outside the packet then an exception is thrown.
In IPv6 the payload is not checksummed it is up to the protocol to checksum its own payload. The checksum includes a pseduo header that is described in RFC 2460 section 8.1
Parameters:
| src | Source address of packet. |
| dst | Destination address of packet. |
| data | pointer to payload. |
| len | length of payload. |
| checksum_offset | offset of checksum in the payload. |
| protocol | protocol number. |
