Hi Chuan, From what I have seen the DPDK driver should disable HW LLDP by default unless your XL710 firmware is not up-to-date and has a bug where disabling HW LLDP can lockup the rx path (fixed from NVM 6.01(for X710 XL710 XXV710)/3.33(for X722) or later according to the source). If you use the native VPP AVF driver, you'll have to disable LLDP on the Linux PF directly (eg. 'echo lldp stop > /sys/kernel/debug/i40e/command'). We cannot selectively enable/disable it per VF it seems.
