Description Jose Luis Duran 2023-04-03 17:16:58 UTC 
When creating vlan sub-interfaces from an epair, and then destroying the parent epair interface, the child interfaces are not destroyed:

# ifconfig epair create
epair0a

# ifconfig epair0a.1 create
# ifconfig -l
... epair0a epair0b epair0a.1

# ifconfig epair0a destroy
# ifconfig -l
... epair0a.1

is this on CURRENT only?
that is: is this a (netlink related) regression?

This issue is present on every supported FreeBSD version.  It is not related to netlink.

Although on netlink it complains upon create/destroy:
[nl_iface] get_operstate_ether: error calling SIOCGIFMEDIA on epair0a.1: 22
