The group in charge of LS1028A software doesn't do any LLDP specific testing.
That being said, there are no known problems surrounding it, since there is no special platform-level support required for LLDP.
In OpenIL 1.8, one can enable BR2_PACKAGE_LLDPD. For testing, the resulting rootfs can be deployed on 2 LS1028A-RDB boards, and a cable connecting eno0 to swp0 can be added.
The lldpd daemon is started automatically by /etc/init.d/S60lldpd. So, the lldpcli can be used directly:
Board 1:
[lldpcli] # show neighbors
-------------------------------------------------------------------------------
LLDP neighbors:
-------------------------------------------------------------------------------
Interface: swp0, via: LLDP, RID: 1, Time: 0 day, 00:00:14

So the 2 boards see each other.
It is not mandatory to use lldpd, this is just an example.
