Author: luigi Date: Wed Aug 20 17:33:32 2014 New Revision: 270235 URL: http://svnweb.freebsd.org/changeset/base/270235 Log: MFC 259907 (dates back to december) use the correct netmap <-> nic slot mapping on the transmit ring for 'lem'. This bug would manifest only in netmap mode and on packets transmitted after a NIC reset while netmap mode is active.
