Bug ID: 256610
Summary: Kernel panic with ngtee
Product: Base System
Version: 13.0-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me

With the following in /etc/rc.conf:
ipfw_netflow_enable="YES"
ipfw_netflow_rule=1111
ipfw_netflow_ip="192.168.1.2"
ipfw_netflow_port=9995
ipfw_netflow_version=9
I can reliably get a kernel panic as soon as there is network traffic between a
host on the LAN and a jail whose IPv4 address is attached to a VLAN interface
which also has a bridge by vm-bhyve. 192.168.1.2 is another jail on the local
machine. This is a kernel compiled with INVARIANTS but it also panics without,
and did so on 13.0-RELEASE.
