ebdff66c8b ARP: Add support for the case where there are multiple networks: One being Etherenet and the other not (say slip or perhaps someday PPP). In that case, we need to suppress ARP-related operations on the SLIP/PPP interface only 2014-11-14 18:25:33 -06:00

e03c764d92 I don't think that the net_route function has ever worked correctly. The source ip was updated in the match struct instead of the route ip. From Brennan Ashton. 2014-11-14 16:45:25 -06:00

ad9b3f8ab8 wdog.h does not contain any application interface, only internal OS interface. Further, it is non-standard. Move wdog.h from include/ to include/nuttx. For the same reason, move the description of the watchdog timer interfaces from the Users Guide to the Porting Guide. 2014-08-21 11:16:55 -06:00

21add71646 ARP reuestion logc needs to do the right thing if (1) the address is a broadcast or multicast address, and (2) if the IP address lies outside of the network. Thanks to Manuel Stuehn 2014-08-20 07:09:02 -06:00

6e04518e4a If CONFIG_NET_ARP_SEND is enabled, then all ICMP, TCP, and UDP send operations will call arp_send() before attempting the real send operation. arp_send() will check if the the IP address mapping is in the ARP table and, if not send ARP requests periodically until it is. This eliminates losing the first outgoing message because there is not mapping in the ARP table. 2014-08-18 16:22:14 -06:00
