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!)
