Default netstat -s -p ip output meaning

Hey, I'd like to ask you all a question, that is ought to be simple -- what exactly does each field of netstat -s -p ip output mean ?, E.g.

        26740727 total packets received
        14 bad header checksums
        0 with size smaller than minimum
        0 with data size < data length
        0 with ip length > max ip packet size
        0 with header length < data size
        0 with data length < header length
        0 with bad options
        0 with incorrect version number
        365 fragments received
        0 fragments dropped (dup or out of space)
        0 fragments dropped after timeout
        122 packets reassembled ok
        26734571 packets for this host
        5847 packets for unknown/unsupported protocol
        0 packets forwarded (0 packets fast forwarded)
        37 packets not forwardable
        0 packets received for unknown multicast group
        0 redirects sent
        28384081 packets sent from this host
        0 packets sent with fabricated ip header
        0 output packets dropped due to no bufs, etc.
        0 output packets discarded due to no route
        6054 output datagrams fragmented
        27879 fragments created
        0 datagrams that can't be fragmented
        0 tunneling packets that can't find gif
        0 datagrams with bad address in header
Im especially interested in 'packets not forwardable'.
What does presence of "not forwardable packets" mean ? Thanks in advance for Your kind help.
