lldpd: unable to send packet on real device

Notes on lldpd errors after a network restart, with example log messages and restarting the lldpd service to reopen its interfaces.

Straightforward, if you get these error messages:

Jan 26 10:27:33 c**.com lldpd[3083]: unable to send packet on real device for ens9f1: No such device or address
Jan 26 10:27:35 c**.com lldpd[3083]: unable to send packet on real device for enp132s0f0: No such device or address
Jan 26 10:27:35 c**.com lldpd[3083]: unable to send packet on real device for enp132s0f1: No such device or address
Jan 26 10:27:40 c**.com lldpd[3083]: unable to send packet on real device for ens9f0: No such device or address

You will need to restart lldpd services and everything will be just fine.

This is pretty much expected when you restart the network, as lldpd doesn't seem to re-open interfaces. If you restart it after a network restart, it clears up.
