Author: kp Date: Sun Nov 18 11:55:56 2018 New Revision: 340565 URL: https://svnweb.freebsd.org/changeset/base/340565 Log: MFC r340065: pfsync: Make pfsync callbacks per-vnet The callbacks are installed and removed depending on the state of the pfsync device, which is per-vnet. The callbacks must also be per-vnet.
