>Description:
[src/sys/dev/pci/if_et.c:2055] -> [src/sys/dev/pci/if_et.c:2056]: (warning) Opposite conditions in nested 'if' blocks lead to a dead code block.


Source code is


    if (error) {
        if (!error) {
            bus_dmamap_unload(sc->sc_dmat, sc->sc_mbuf_tmp_dmap);
            error = EFBIG;
            aprint_error_dev(sc->sc_dev, "too many segments?!\n");
        }
