ifconfig lagg0 with underlying devices, such as Mellanox CX6-DX, which support SIOCSIFCAPNV. Ensure ifconfig doesn't present an error like:
```
# ifconfig lagg0
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
ifconfig: ioctl (SIOCGIFCAPNV): Invalid argument
```
Ensure caps from both if_capabilities2 (rxtls) and if_capabilities can be enabled, and settings are propagated between lagg0 and lagg ports.
