Bug#1010659: systemd-networkd LLDP transmit broken since v250

Package: systemd
Version: 250.4-1

Dear Maintainer,

Since systemd v250 (bookworm/testing), the LLDP packets transmitted by
systemd-networkd (with EmitLLDP=on) are malformed, causing debian systems
running bookworm to be unidentifiable by managed switches.

This is a regression relative to v247 (bullseye/stable).

The issue has been fixed upstream in git:
