To be able to do Ethernet_II framing on one interface and 802.3 on another I have used if_ef.ko. I then noticed that "... kernel: nd6_storelladdr failed" gets logged often and after a while all mbufs are used. It turned out that in sys/net/if_ethersubr.c in ether_output() when nd6_storelladdr() fails, it does a return(0) and does not free the mbuf. I checked -current and it is still like that. Now the reason it fails is that the ef(4) device use an ifp->if_type (IFT_XETHER) that nd6_storelladdr() does not expect. Oh as a workaround I have configured route6d to ignore fxp1f0.
