my frr log seems to be spewing the following lines

zebra: extended error: invalid link address

netlink-dp error: invalid argument, type=rtm_newneigh(28), seq=..., pid=...

nl_batch_read_resp: netlink error message seq=...

nlmsghdr [len=64 type(2) error flags=(0x0300) {dump,(root|replace|capped),(match|exclude|ack_tlvs)} seq=... pid=...]

can anyone suggest some debug settings that i can turn on to help figure out what's going on.  i'm not entirely sure when this started, i only noticed it because my logs dir filled up
