    [wr_streamers] prevent sending streamer frames when link is down · ba95756c
    Maciej Lipinski authored
    sending streamer frames when link is down causes weird behavior:
    - the frames are counted as sent, while they are not
    - some frames are dropped, depending on PHY implementation
    - at startup, the link is reseted by software, so link is up for
      some time, then it goes down, than up again... mess
    
    two additions:
    - the dreq_o signal is gated with link_ok_i, so that frames cannot
      be sent when link is down
    - startup counter which delays the start of sending frames
