    nfe_encap() is totally broken.  It is setting each ring segment to
    NFE_TX_VALID as it goes, before it finishes writing out all the segments.
    In fact, it seems to be setting NFE_TX_VALID before it sets the LASTFRAG
    flag!  It's amazing that it works at all.
Yeah, that's it!!  Thank you very much!!  I didn't figure out the real
cause in the old version, but instead went to the sidetrack: adding a
delay in nfe_encap() :-P
