MACsec/IEEE 802.1AE is useful to secure communication to and
from endpoints at Layer 2.
Starting with 4.6, the linux kernel provides a universal
macsec driver for authentication and encryption of traffic
in a LAN, typically with GCM-AES-128, and optional replay
protection.

Note:
LEDE can utilize MACsec with a static connectivity association
key (static PSK) with the ip-full package installed.
