Network booting no longer works

[reraikes]

Using RPF's "Network boot your Raspberry Pi" tutorial (https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/net_tutorial.md), a Raspberry Pi 3B+ client network boots perfectly from a Raspberry Pi 4B server using firmware versions up through and including 5.10.27 (acf3b95). Monitoring /var/log/daemon.log displays:
