Description

Packet capture fails to start if interface is enc0 (IPSec) and any custom filter configuration present.
"Any" type filters run normally.
tested on Version 23.05-RC (amd64)
built on Thu May 11 06:04:57 UTC 2023
FreeBSD 14.0-CURRENT

I assume it tries to run the 'not vlan' option on enc0 and gets this result:
[23.05-RC][]/root: /usr/sbin/tcpdump -ni enc0 -c 1000 -U -w - '((host 10.0.1.2)) and ((not vlan))'
tcpdump: no VLAN support for OpenBSD encapsulated IP
