[systemd-devel] LLDP from Zyxel – "Operation not supported"

I enabled LLDP receive for eth* in networkd. It recognizes outgoing packets
sent by lldpd (on the computer itself) and by ladvd (on pfSense), but
chokes on incoming packets sent by a Zyxel switch:

> LLDP: Receive frame failed: Operation not supported

Attaching the actual packet.

(By the way, `networkctl lldp` is a bit boring – it'd be more useful to
show the SysName instead of the TTL...)
