nuttx/net:Support to PMTUD RFC 1191 When a router is unable to forward a datagram because it exceeds the MTU of the next-hop network and its Don't Fragment bit is set, the router is required to return an ICMP Destination Unreachable message to the source of the datagram, with the Code indicating "fragmentation needed and DF set". To support the Path MTU Discovery technique specified in this memo, the router MUST include the MTU of that next-hop network in the low-order 16 bits of the ICMP header field that is labelled "unused" in the ICMP specification [7]. The high-order 16 bits remain unused, and MUST be set to zero. Thus, the message has the following format: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type = 3 | Code = 4 | Checksum | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | unused = 0 | Next-Hop MTU | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Internet Header + 64 bits of Original Datagram Data | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ RFC 1185 Packet Too Big Message 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type | Code | Checksum | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | MTU | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | As much of invoking packet | + as will fit without the ICMPv6 packet + | exceeding 576 octets | IPv6 Fields: Destination Address Copied from the Source Address field of the invoking packet.

Description A Packet Too Big MUST be sent by a router in response to a packet that it cannot forward because the packet is larger than the MTU of the outgoing link.

This change adds support for semi-standard IPPROTO_ICMP AF_INET datagram sockets. This replaces the old ad hoc, nonstandard way of implementing ping with a more standard, socket interface. Squashed commit of the following: net/icmp: Finishes off icmp_recvfrom(). net/icmp: Add readahead support for IPPROTO_ICMP sockets. net/icmp: Add poll() support for IPPROTO_ICMP sockets. net/icmp: Add a connection structure for IPPROTO_ICMP sockets. net/icmp: Implements sendto for the IPPROTO_ICMP socket. net/icmp: Move icmp_sendto() and icmp_recvfrom() to separate files. They are likely to be complex (when they are implemented). net/icmp: Hook IPPROTO_ICMP sockets into network. Fix some naming collisions. Still missing basic ICMP send/receive logic. configs: apps/system/ping current need poll() enabled. configs: All defconfig files that use to enable low-level support must now enabled CONFIG_SYSTEM_PING. net/icmp: Adds basic build framework to support IPPROTO_ICMP sockets.

Enable support for IPPROTO_ICMP sockets. These sockets are needed
This commit adds support for semi-standard IPPROTO_ICMP6 sockets. This is a replacement for the non-standard ICMPv6 ping support that violated the portable POSIX OS interface. Squashed commit of the following: net/icmpv6: IPPROT_ICMP6 socket logic now builds without error. net/icmpv6: Add support for read-ahead and poll(). Initial commit is just cloned from ICMP with the appropriate name changes. configs/: All defconfig filess that include CONFIG_NET_ICMPv6_SOCKET=y need to select CONFIG_SYSTEM_PING6=y and deselect CONFIG_DISABLE_POLL. Update NSH documention to show that ping6 is now a built in command. net/icmpv6: Add icmpv6_sendto.c and icmpv6_recvfrom.c. Initial versions are just clones from icmp/ with appropriate name changes. net/icmpv6: Clone some ICMP socket logic as the beginning of support for ICMPv6 socket support. Rename CONFIG_NET_ICMPv6_PING to CONFIG_NET_ICMPv6_SOCKET. Move prototype for icmpv6_ping from include/nuttx/net/icmpv6 to net/icmpv6/icmpv6.h

be allocated at a later time, as the system needs them. Else this
will be the maximum number of connections available to the system
at all times.

and it will be free'd when no longer needed.
Setting this to 2 or more will allocate the connections in
batches (with batch size equal to this config). When a
connection is no longer needed, it will be returned to the
free connections pool, and it will never be deallocated!
