Worth trying That was probably a bit too brief. What I meant was: Try changing the last argument to ipv6_stub->ndisc_send_na() from "false" to "true" and see if that makes any difference. This is the "inc_opt" bool, which decides whether or not we include the ND_OPT_TARGET_LL_ADDR option. Since the firmware is buggy enough to require NAs in the first place, it is not surprising if it wants this absolutely pointless option as well. I should have included it in the first place.
