Author: np Date: Tue Jan 29 20:59:22 2013 New Revision: 246093 URL: http://svnweb.freebsd.org/changeset/base/246093 Log: Provide a statistic to track the number of drops in each of the port's txq's buf_ring. The aggregate for all the queues of a port is already provided in ifnet->if_snd.ifq_drops. MFC after: 3 days.
