* TODO: the ARP layer is not protected against concurrent access. If
you run from a multitasking OS, serialize access to ARP (called from
your network device driver and from a timeout thread.)
Is anyone have some informations to know where to protect the ARP layer ?
The gratuitous ARP seems to be disable in netif.c (in netif_set_ipaddr(...)). Anyone knows why? Is it done directly in etharp.c ? I don't find it...
#if 0 /* only allowed for Ethernet interfaces TODO: how can we check? */
/** For Ethernet network interfaces, we would like to send a
* "gratuitous ARP"; this is an ARP packet sent by a node in order
* to spontaneously cause other nodes to update an entry in their
* ARP cache. From RFC 3220 "IP Mobility Support for IPv4" section 4.6.
etharp_query(netif, ipaddr, NULL);
Thank you for your informations...
