Hello guys. 

I had a lot of problems with the vm-bhyve NAT network. That's why I looked for
alternatives and took the opportunity to study cases of using Netgraph and
netmap/VALE with bhyve.

And so I think I found some bugs in 14-CURRENT.

> a. After some time away from the PC, there is a disconnection with the WiFi network.
> b. When I delete a VALE network that was connected to wlan0 before disconnecting the network, FreeBSD freezes;

The scenario is this:

- 1. After some time away from the PC, there is a disconnection with the WiFi
network. It looks like it's connected, but it doesn't work;

- 2. I enter the command: service netif restart wlan0

- 3. The network works again;

- 4. When I delete a VALE network that was connected to wlan0 before
disconnecting the network, FreeBSD freezes;

I've tested it several times, and the same thing happens.

My wpa_supplicant version:

```
$ wpa_supplicant -v
wpa_supplicant v2.10
