Ok, mea culpa
I figured it out..
Luigi.. does this fix it?
(void)memcpy(&itaddr, ea->arp_tpa, sizeof (itaddr));
TAILQ_FOREACH(ia, &in_ifaddrhead, ia_link) {
#ifdef BRIDGE
/*
* For a bridge, we want to check the address irrespective
* of the receive interface. (This will change slightly
* when we have clusters of interfaces).
*/
#define BRIDGE_TEST (do_bridge)
#else
#define BRIDGE_TEST 0 /* cc will optiise the test away */
#endif
if ((BRIDGE_TEST) || (ia->ia_ifp == &ac->ac_if)) {
maybe_ia = ia;
if ((itaddr.s_addr == ia->ia_addr.sin_addr.s_addr) ||
(isaddr.s_addr == ia->ia_addr.sin_addr.s_addr)) {
break;
}
}
}
if (maybe_ia == 0) {
m_freem(m);
return;
}
myaddr = ia ? ia->ia_addr.sin_addr : maybe_ia->ia_addr.sin_addr;
if (!bcmp((caddr_t)ea->arp_sha, (caddr_t)ac->ac_enaddr,
sizeof (ea->arp_sha))) {
m_freem(m); /* it's from me, ignore it. */
return;
}
