Field Documentation

disp_ecn

uint8_t sixlowpan_sfr_t::disp_ecn

Dispatch and explicit congestion notification (ECN) flag.

In network byte-order the 7 most significant bits are the dispatch (7 bits) and the least significant bit is the ECN flag:

+-+-+-+-+-+-+-+-+
|  Dispatch   |E|
+-+-+-+-+-+-+-+-+

For sixlowpan_sfr_ack_t the ECN flag represents the ECN echo flag.

This module provides helper functions to set, get, check these fields accordingly:

• sixlowpan_sfr_is()
• sixlowpan_sfr_set_ecn()
• sixlowpan_sfr_clear_ecn()
• sixlowpan_sfr_ecn()
• sixlowpan_sfr_rfrag_set_disp()
• sixlowpan_sfr_rfrag_is()
• sixlowpan_sfr_ack_set_disp()
• sixlowpan_sfr_ack_is()
