When in limited logging mode, quit logging broadcast
packets dropping/rejecting.

    Neil,

    Actually, we have an interesting condition here. On general
    ethernet applications we want to drop / reject the broadcasts.
    On a home network using a cable modem as our link we will
    want to not drop these. It seems (I'm still looking for the RFC
    on this) that by design most cable modems send a steady
    stream of BCAST packets destined for bootpc from the
    ethernet side of the modem. This is presumably somekind of
    IP management technique. While I can't think of the necesity
    for this, it is aparently the way they are intended to behave.

    That said, while looking into not logging these rejections,
    would it be possible to add support for accepting broadcast
    packets from specific hosts even though the DSTADDR is
    255.255.255.255 ? TRUSTED does not pick these up as the
    DSTADDR is not that of the extif.

    Many thanks for all of your hard efforts.

    My apologies for not including my address in that comment
    regarding cable modems. I'm using lynx and missed the login.
