When LLDP is configured, on all interfaces or on specific interfaces LLDP packets are sent but nothing is received.
With lldpcli this can be confirmed
lldpcli show stat Interface: eth1 Transmitted: 7 Received: 0 Discarded: 0 Unrecognized: 0 Ageout: 0 Inserted: 0 Deleted: 0
And old discussion on Intel forum suggests this has ben long existing in the X710 network card.
I can confirm it also exists on Intel X722 interfaces.
The forum suggests disabling the lldp handling on the nic and let the kernel take care of it.
echo lldp stop > /sys/kernel/debug/i40e/<ifid>/command
This needs to be run as root and the right interface ids need to be picked for the specific cards.
