| #define CONFIG_GNRC_SIXLOWPAN_FRAG_RBUF_DEL_TIMER (0U) |
Deletion timer for reassembly buffer entries in microseconds.
Time to pass between completion of a datagram and the deletion of its reassembly buffer entry. If this value is 0, the entry is dropped immediately. Use this value to prevent re-creation of a reassembly buffer entry on late arriving link-layer duplicates.
| #define CONFIG_GNRC_SIXLOWPAN_FRAG_RBUF_DO_NOT_OVERRIDE |
Do not override oldest datagram when reassembly buffer is full.
When not set, it will cause the reassembly buffer to override the oldest entry when a fragment for a new datagram is received.

| #define CONFIG_GNRC_SIXLOWPAN_ND_AR_LTIME (15U) |
Registration lifetime in minutes for the address registration option.
This value should be adapted to the devices power-lifecycle so that it is greater than the time the device spends sleeping.
| #define CONFIG_GNRC_SIXLOWPAN_SFR_DG_RETRIES 0U |
| #define CONFIG_GNRC_SIXLOWPAN_SFR_ECN_FQUEUE_DEN 2U |
The denominator for the factor for when to mark ECN on frame queue state.
When gnrc_sixlowpan_frag_sfr_ecn_fqueue is compiled in, nodes will set the ECN bit of an RFRAG header when the frame queue for SFR is filled by CONFIG_GNRC_SIXLOWPAN_SFR_ECN_FQUEUE_NUM / CONFIG_GNRC_SIXLOWPAN_SFR_ECN_FQUEUE_DEN
| #define CONFIG_GNRC_SIXLOWPAN_SFR_ECN_FQUEUE_NUM 1U |

When gnrc_sixlowpan_frag_sfr_ecn_fqueue is compiled in, nodes will set the ECN bit of an RFRAG header when the frame queue for SFR is filled by CONFIG_GNRC_SIXLOWPAN_SFR_ECN_FQUEUE_NUM / CONFIG_GNRC_SIXLOWPAN_SFR_ECN_FQUEUE_DEN

When gnrc_sixlowpan_frag_sfr_ecn_if_in is compiled in, nodes will set the ECN bit of an RFRAG header when the message queue of the incoming netif is filled by CONFIG_GNRC_SIXLOWPAN_SFR_ECN_IF_IN_NUM / CONFIG_GNRC_SIXLOWPAN_SFR_ECN_IF_IN_DEN
| #define CONFIG_GNRC_SIXLOWPAN_SFR_ECN_IF_OUT_DEN 2U |
The denominator for the factor for when to mark ECN on the outgoing netif output queue state.
When gnrc_sixlowpan_frag_sfr_ecn_if_out is compiled in, nodes will set the ECN bit of an RFRAG header when the output queue of the outgoing netif is filled by CONFIG_GNRC_SIXLOWPAN_SFR_ECN_IF_OUT_NUM / CONFIG_GNRC_SIXLOWPAN_SFR_ECN_IF_OUT_DEN

| #define CONFIG_GNRC_SIXLOWPAN_SFR_FRAG_RETRIES 2U |
| #define CONFIG_GNRC_SIXLOWPAN_SFR_INTER_FRAME_GAP_US 100U |
Default minimum amount of time between transmissions in microseconds (InterFrameGap)
All packets to a same destination, and in particular fragments, may be subject to receive while transmitting and hidden terminal collisions with the next or the previous transmission as the fragments progress along a same path. The InterFrameGap protects the propagation of to one transmission before the next one is triggered and creates a duty cycle that controls the ratio of air and memory in intermediate nodes that a particular datagram will use.
| #define CONFIG_GNRC_SIXLOWPAN_SFR_MAX_ARQ_TIMEOUT_MS 700U |
| #define CONFIG_GNRC_SIXLOWPAN_SFR_MAX_FRAG_SIZE 112U |
Default maximum value for fragment size (MaxFragmentSize)
It must be lower than the minimum MTU along the path. A large value augments the chances of buffer bloat and transmission loss. The value must be less than 512 if the unit is defined for the PHY layer is the octet.

Default minimum value of window size that the sender can use (MinWindowSize)
| #define CONFIG_GNRC_SIXLOWPAN_SFR_MOCK_ARQ_TIMER 0U |
Deactivate automatic handling of ARQ timer.
This requires an external source (e.g. a test application) to call gnrc_sixlowpan_frag_sfr_arq_timeout() for 6LoWPAN selective fragment recovery to still work properly.
| #define CONFIG_GNRC_SIXLOWPAN_SFR_OPT_ARQ_TIMEOUT_MS CONFIG_GNRC_SIXLOWPAN_SFR_MAX_ARQ_TIMEOUT_MS |
