Public bug reported:
Hi,
Per the Intel community [1], for Intel X710 controllers, the NIC is
meant to handle LLDP directly. Unfortunately, this doesn't play well
with lldpd:
| hloeung@cumulus:mgmt:~$ net show lldp | grep swp24
| swp24 10G Trunk/L2 37383638-3530-5A43-3238-333330423954 Unknown
It is known in upstream lldpd[2] with a fix proposed to work around this
by disabling handling of LLDP in the NIC[3]. Can we please backport this
to Focal?
The suggested workaround is:
| for i in $(sudo ls /sys/kernel/debug/i40e); do
| echo lldp stop | sudo tee /sys/kernel/debug/i40e/${i}/command
| done
