Long for your fix. Thanks.
It's still at least a week or so out...
I have a doubt for the issue.
Alfred should send the info by multicast packets. So the packet's dst
mac address should be multicast mac address.
The packet with multicast mac address should be received by all group
member, isn't it?
Why does the mesh point need peer's mac address for sending the info?
The rest of the devs may be able to answer better, but I believe it is
how alfred does its data storage and mapping of the source. When I
looked at this a few months ago the way it was using the ARP table to
pull the MAC address didn't work right and required a separate ARP
request to have it work properly.
When I have a chance to dig back into it and develop the fix I can
provide more details, but that's what I recall right now. It didn't
make sense to me at first either based on the symptoms, but when I dug
through the code I realized that was what was required and just didn't
have time to put the fix in then.

I setup a testbed like this. (BBN = backbone
Switch ---------->BBN1 --------------->MP1
MP1 and MP2 may select BBN1 or BBN2 as gateway.
On both MP1 and MP2, I enable Alfred and batadv-vis as follows:
alfred -i br0 -4 22.214.171.124 -m &
batadv-vis -i bat0 -s
Looks like you are using the experimental IPv4 support which I
want to actively support. So Jonathan Haws should take care of
I am aware of this issue, but was under the impression I was the only
one it affected. I'm working on a fix (basically check the ARP table
and if a record doesn't exist for the MAC then run an ARP query; if
that query fails then report a error) and I hope to have it working

We have been working around this issue in the same manner as you
describe for the time being.
