New Revision: 368054
URL: https://svnweb.freebsd.org/changeset/base/368054
Log:
Add missing NET_EPOCH_EXIT() to if_bridge
In r367706 one return in bridge_input() did not NET_EPOCH_EXIT(), which caused
seemingly random panics on the next use of NET_EPOCH.
Direct commit to stable/12, because this code is different in CURRENT.
