Hi

I am not sure where else to report this, but I would like to report a problem.

1. I create a tap device using "tunctl -t tap-test".

2. I then configure it with an ip address using "ifconfig tap-test
10.0.0.1 up".

3. Next. I start "arping -I tap-test 10.0.0.5" on one terminal and

4. I run "tcpdump -i tap-test" on another terminal to see if I can see
the ARP packets on the tap interface tap-test

I tried the above steps on two separate machines one where the linux
kernel version (determined by uname -r) says 3.0.0-17-generic and
another one where it says 2.6.32-5-amd64 . I am wondering if something
changed in the driver between the kernel versions or whether some
kernel variable is filtering out these ARP messages.
