Enabled via -4 expert option where multicast group address is specified. This option will disable IPv6 communication and is intended for use in networks which do not support IPv6 addressing.
When this option is enabled, all IPv6 communication is disabled. Combining IPv4 and IPv6 alfred nodes is unsupported.
Hardware address handling done by submitting queries to the local ARP cache rather than forcing an ARP request.
Thanks Jonathan for your patch! I've just looked through the patch and discussed the matter with Sven yesterday. We are both not too big fans of supporting IPv4, but since it helps your scenario and you supplied a well written patch which properly abstracts the address mode and has separate IPv4/ IPv6 functions, I think we can adopt it.
Just two general questions/remarks:
* I do not want to give support for IPv4-related questions of users. Would you be available to maintain and answer questions regarding the IPv4 support?
I'd be happy to answer questions, but it would be best if those questions are directed to the list and my address is in the CC field. That way I'll definitely see it and can answer. If it just goes to the list in general I'll very likely miss the message. Is that someting that could be added to the Wiki?
* Do you plan to provide OpenWRT support as well? (This is more out of curiosity)
I wasn't planning on OpenWRT support. What would be entailed? When I hear OpenWRT, I think of the firmware I can load onto my old Linksys WRT54G AP. Would it simply be testing these changes on that device?
