3b74cfecc2 net/route: Support longest prefix match for routing 
Support longest prefix match routing described as "Longest Match" in
RFC 1812, Section 5.2.4.3, Page 75.

Introduced `prefixlen` to indicate the prefix length of currently
founded route, and only looks up for longer prefix in all later steps.

ae78a925eb Add support for an in-memory routing table cache in order to improve performance when the routing table is retained in a file. The cache holds the most recently used routing table entries and so can eliminate some file access. 
Squashed commit of the following:

    net/route:  Flush in cache when any entry is deleted from the routing table.  When a router matching an IP address is found, add the routing table entry to the cache.

    net/route:  Add utility functions to manage an in-memory cache to improve performance when use a file-based routing table.

12c4c4c8a6 In some cases, packets are still not sent behind the router. I found that NuttX sends the ARP requests not to the router but to the target. Mistake in file net/route/netdev_router.c. From Aleksandr Kazantsev 2017-09-20 13:19:05 -06:00

2663538b0a Networking: Replace all references to the macros net_ipaddr_copy, net_ipaddr_hdrcopy, net_ipaddr_cmp, net_ipaddr_hdrcmp, and net_ipaddr_maskcmp with the appropriate IPv4 or IPv6 version of the macro (such as net_ipv4addr_copy). The goal is to support both IPv4 and IPv6 simultaneously. This requires that the macros be distinct and not conditionally defined to one on or the other. 2015-01-16 13:01:08 -06:00

5e938941a6 Networking: Replace all references to net_ipaddr_t with either in_addr_t on net_ipv6addr_t. The goal is to support both IPv4 and IPv6 simultaneously. This requires that the two types be distinct and not conditionally typedef'ed to net_ipaddr_t. 2015-01-16 12:30:18 -06:00
