Fragmentation is on by default. config NET_6LOWPAN_FRAMELEN int "IEEE802.15.4 MAC Frame Length" default 127 range 127 999999 ---help--- Some wireless devices may use non-standard frame lengths. This setting should never be smaller than 127. choice prompt "6loWPAN Compression" default NET_6LOWPAN_COMPRESSION_HC06 config NET_6LOWPAN_COMPRESSION_IPv6 bool "IPv6 Dispatch" ---help--- Packets compression when only IPv6 dispatch is used. There is no compression in this case, all fields are sent inline. We just add the IPv6 dispatch byte before the packet. config NET_6LOWPAN_COMPRESSION_HC1 bool "6loWPAN HC1" ---help--- Compress IP/UDP header using HC1 and HC_UDP config NET_6LOWPAN_COMPRESSION_HC06 bool "6loWPAN HC06" ---help--- Compress IP/UDP header using HC06 compression endchoice # 6loWPAN Compression config NET_6LOWPAN_COMPRESSION_THRESHOLD int "Lower compression threshold" default 63 depends on !NET_6LOWPAN_COMPRESSION_IPv6 ---help--- CONFIG_NET_6LOWPAN_COMPRESSION_THRESHOLD sets a lower threshold for when packets should not be compressed. config NET_6LOWPAN_MINPORT hex "Minimum port nubmer" default 0xf0b0 depends on NET_6LOWPAN_COMPRESSION_HC1 ---help--- HC1 compression of UDP headersis feasible only if both src and dest ports are between CONFIG_NET_6LOWPAN_MINPORT and CONFIG_NET_6LOWPAN_MINPORT + 15, inclusive. All nodes must agree on the value of CONFIG_NET_6LOWPAN_MINPORT if NET_6LOWPAN_COMPRESSION_HC06 config NET_6LOWPAN_MAXADDRCONTEXT int "Maximum address contexts" default 1 ---help--- If we use IPHC compression, how many address contexts do we support? config NET_6LOWPAN_MAXADDRCONTEXT_PREFIX_0_0 hex "Address context 0 Prefix 0" default 0xaa ---help--- Prefix 0 for address context ze0ro (assumes CONFIG_NET_6LOWPAN_MAXADDRCONTEXT >= 0) config NET_6LOWPAN_MAXADDRCONTEXT_PREFIX_0_1 hex "Address context 0 Prefix 1" default 0xaa ---help--- Prefix 1 for address context 0 (assumes CONFIG_NET_6LOWPAN_MAXADDRCONTEXT >= 0) config NET_6LOWPAN_MAXADDRCONTEXT_PREINIT_1 bool "Pre-initialize address context 1" default n ---help--- Preinitialize address context 1 for better header compression (Saves up to 13 bytes per 6lowpan packet).

If this option is selected, then an 8-byte Rime address will be used. config NET_6LOWPAN_MAXAGE int "Packet reassembly timeout" default 20 ---help--- Timeout for packet reassembly at the 6lowpan layer in units of seconds (should be < 60s) config NET_6LOWPAN_MAX_MACTRANSMITS int "Max MAC transmissions" default 4 ---help--- CONFIG_NET_6LOWPAN_MAX_MACTRANSMITS specifies how many times the MAC layer should resend packets if no link-layer ACK wasreceived. This only makes sense with the csma_driver. config NET_6LOWPAN_MAXPAYLOAD int "Max packet size" default 102 ---help--- NET_6LOWPAN_MAXPAYLOAD specifies the maximum size of packets before they get fragmented. The default is 127 bytes (the maximum size of a 802.15.4 frame) - 25 bytes (for the 802.15.4 MAClayer header). This can be increased for systems with larger packet sizes. config NET_6LOWPAN_MTU int "6LoWPAN packet buffer size" default 1294 range 590 1518 depends on NET_6LOWPAN_FRAG ---help--- Packet buffer size. This size includes the TCP/UDP payload plus the size of TCP/UDP header, the IP header, and the Ethernet header. This value is normally referred to as the MTU (Maximum Transmission Unit); the payload is the MSS (Maximum Segment Size). NOTE that this option depends on fragmentation support. By supporting fragmentation, we can handle quite large "logical" packet sizes. Without fragmentation support, the MTU is equal to the frame size and that has already been selected. config NET_6LOWPAN_TCP_RECVWNDO int "6LoWPAN TCP receive window size" default 1220 if NET_6LOWPAN_FRAG default 102 if !NET_6LOWPAN_FRAG depends on NET_TCP ---help--- The size of the advertised receiver's window. Should be set low (i.e., to the size of the IEEE802.15.4 MTU or frame payload) if the application is slow to process incoming data, or high (32768 bytes) if the application processes data quickly. config NET_6LOWPAN_DUMPBUFFER bool "Enable dumping of buffer data" default n depends on DEBUG_NET_INFO ---help--- Enable dumping of all packet and frame buffers coming into and out of the 6loWPAN logic. This will generate a large volume of data if selected. endmenu # 6LoWPAN Configuration
