Hi All,
I have a question on the function ip_addr_isbroadcast():
Why do we check for destination address even before we've determined
if the network interface supports broadcast or not? Shouldn't that be
the first check?
<snip>
...
/* all ones (broadcast) or all zeroes (old skool broadcast) */
if ((~addr2test == IP_ADDR_ANY_VALUE) ||
(addr2test == IP_ADDR_ANY_VALUE))
return 1;
/* no broadcast support on this network interface? */
else if ((netif->flags & NETIF_FLAG_BROADCAST) == 0) <===
/* the given address cannot be a broadcast address
* nor can we check against any broadcast addresses */
return 0;
...
</snip>
Regards,
-mandeep
