arp Remove CONFIG_NET_MULTILINK. This increases code size by a little, but greatly reduces the complexity of the network code. 2017-08-08 15:26:09 -06:00
devif 6LoWPAN: The original, Contiki-based design used only a single buffer for reassemblying larger packets. This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently. These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets. The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address. This assures that there can be be no corruption of the reassembly once it has started. 2017-08-26 10:00:47 -06:00
icmp Remove CONFIG_NETDEV_MULTINIC. This increases code size by a little, but greatly reduces the complexity of the network code. 2017-08-08 14:24:12 -06:00
icmpv6 net/icmpv6: Eliminate a warning 2017-08-10 07:27:40 -06:00

igmp networking: Move a little more to the inet/ subdirectory. 2017-08-07 13:03:23 -06:00
inet Networking: Remove driver based backlog support. This affects the entire network, but is used by only one driver. The only supported with of supported RX backlog is via common read-ahead buffering. 2017-08-21 06:28:59 -06:00

local net/local: fix accept for local stream sockets 2017-07-31 07:36:54 -06:00
loopback Fix IPv6 loopback driver that depended on the removed g_ipv6_allonesaddr. Noted by Masayuki Ishikawa 2017-08-09 06:59:55 -06:00
neighbor Networking: Fix netdev_dev_lladdrsize. In some configurations, it could return the wrong size for the address of a packet radio. 2017-08-08 16:27:23 -06:00
netdev Networking: Rethink last fix. We can make this less protocol dependent. 2017-08-23 15:30:56 -06:00
pkt Networking: Remove driver based backlog support. This affects the entire network, but is used by only one driver. The only supported with of supported RX backlog is via common read-ahead buffering. 2017-08-21 06:28:59 -06:00
procfs Network procfs: procfs/net_procfs_route.c building error occur if CONFIG_NET_ROUTE is enabled. Fix suggested by Aleksandr Kazantsev 2017-08-22 10:21:07 -06:00
