<offtopic> Hummm, funny. Last time I saw this was on Windows, and it only ate the packets on PPP. </offtopic>

I just noticed something *very* strange.  I was debugging a
network application with tcpdump, and it appears that

# tcpdump -i wlan0

causes all incoming packets to be consumed.  This includes
pings, TCP traffic (ssh), multicast UDP datagrams, everything.

To compound the oddity, using "-p" to avoid putting wlan0
into promiscuous mode allows traffic to flow again.

Has anybody else seen this?  I haven't tried to reproduce on
the Ethernet, but I will.

Thanks for any help you can render!
