[etherlab-users] ethercat filtering

Hi Mike,

You are right.

But that does not explain, Why the interface gets packets eventhough
the lan cable is removed.
So, i am trying to figure out if the program is wrong or is there
something going on which i am missing.

You could try this on a laptop as well. Not sure whats going on..

Regards,
Sriram
