Well, you know what they say about assumption. :)

Sorry, I'd missed that. Assumption works either way, apparently. O:-)
So -- dnsmasq may ignore a request if it is not authoritative.
Your dnsmasq conf file does not say it is authoritative, and I'll...
assume... that no command line option changes that.
So, maybe your dnsmasq thinks it does not have authority to answer the
discovery request when on WLAN.
Stupid question BTW: how does yor host get its eth and wlan IPs? Does
it ask another DHCP server on the segment, or are they fixed? In the
end, does it get the same or different addresses on both I/Fs?
Anyway: the only difference I see between the requests is the broadcast
flag present for the WLAN packet and absent in the ETH packet, but I
don't see how this could affect dnsmasq.
