Author: hselasky Date: Thu Apr 26 08:58:27 2018 New Revision: 333015 URL: https://svnweb.freebsd.org/changeset/base/333015 Log: Add network device event for priority code point, PCP, changes. When the PCP is changed for either a VLAN network interface or when prio tagging is enabled for a regular ethernet network interface, broadcast the IFNET_EVENT_PCP event so applications like ibcore can update its GID tables accordingly.
