Author: jfv Date: Wed Jul 10 23:14:24 2013 New Revision: 253176 URL: http://svnweb.freebsd.org/changeset/base/253176 Log: Fix to a panic found internally, bad pointer during rxeof processing. Thanks for John Baldwin for catching this. Not clearing the flag member of the rxbuf could result in a NULL mbuf pointer being used. MFC after: 2 days (this needs to get into 9.2!)
