Gregory Nutt fef255e5be This commit adds an as-of-yet untested implemented of UDP write buffering. 
Squashed commit of the following:

    net/udp:  Address most of the issues with UDP write buffering.  There is a remaining issue with handling one network going down in a multi-network environment.  None of this has been test but it is certainly ready for test.  Hence, the feature is marked EXPERIMENTAL.
    net/udp:  Some baby steps toward a corrected write buffering design.
    net/udp:  Remove pesky write buffer macros.
    Eliminate trailing space at the end of lines.
    net/udp:  A little more UDP write buffering logic.  Still at least on big gaping hole in the design.
    net/udp:  Undefined CONFIG_NET_SENDTO_TIMEOUT.
    net/udp:  Crude, naive port of the TCP write buffering logic into UDP.  This commit is certainly non-functional and is simply a starting point for the implementatin of UDP write buffering.
    net/udp:  Rename udp/udp_psock_sendto.c udp/udp_psock_sendto_unbuffered.c.

arp net/arp: Fix IGMP multicast address computation on Nuttx network stack. This change fixes the IGMP address computation to allow multicast UDP messages. The destination address was created with the incorrect bytes of the given IPv4 address. 2018-01-02 11:19:30 -06:00
devif Merged in antmerlino/nuttx/ipfwd-remove-redundant-llheadersize (pull request #548) 2017-11-29 00:54:17 +00:00
icmp net: Fix an error introduced when ICMP and ICMP6 socket support was added in NuttX-7.3. A gratuitous ARP (or solitication) was being sent after receive of the ECHO replay (advertisement). 2018-01-01 11:15:21 -06:00
icmpv6 net: Fix an error introduced when ICMP and ICMP6 socket support was added in NuttX-7.3. A gratuitous ARP (or solitication) was being sent after receive of the ECHO replay (advertisement). 2018-01-01 11:15:21 -06:00

ipforward Merged in antmerlino/nuttx/sixlowpan-mac802154 (pull request #526) 2017-11-01 20:15:21 +00:00
local This commit modifies the Unix domain local socket design. Local sockets are built on top of pipes. The Local socket implementation maintained file descriptors to interrupt with the pipes. File descriptors have the bad property that they are valid only while running on the thread within the task that created the local socket. 2017-11-02 08:23:38 -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 net/: Fix some build issues noted when both IPv4 and IPv6 are enabled. 2017-10-18 11:08:56 -06:00
netdev net/netdev: Add support for the SIOCGIFBRDADDR ioctl() command. 2017-11-22 16:47:04 -06:00
pkt net/pkt: Eliminate a compile error due to missing include and also a warning. 2017-11-29 15:20:15 -06:00
procfs Trivial fix in some comments. 2017-09-20 10:06:26 -06:00
route net/route: Fix a couple of compile-related issues that have crept in sense the last time the file-based routing table was used. 2018-01-05 08:57:22 -06:00
