## Detailed Description

6LowPAN output for IPv6. Uses ND tables for link-layer addressing. Fragments packets to 6LowPAN units.

This implementation aims to conform to IEEE 802.15.4(-2015), RFC 4944 and RFC 6282.

## Function Documentation

## ◆ lowpan6_calc_crc()

u16_t lowpan6_calc_crc | ( | const void * | buf,
|  | u16_t | len
| ) |  |

Calculate the 16-bit CRC as required by IEEE 802.15.4

## ◆ lowpan6_tmr()

void lowpan6_tmr | ( | void |  | ) |

Periodic timer for 6LowPAN functions:

- Remove incomplete/old packets
