Author: adrian Date: Sun Jan 1 01:08:51 2012 New Revision: 229165 URL: http://svn.freebsd.org/changeset/base/229165 Log: If frames are dumped out of the queue, let's at least see what they are. This shows that the majority of the weird traffic I see here are probe frames that haven't been sent out, but I can also trigger this condition by doing ICMP w/ -i 0.3 - enough to trigger the TX during actual scanning, but not fast enough to stop scanning from occuring.
