    revision 1.419\n\nFix fast path for uni directional transfers\n\npure ACK case:\ndrag
    snd_wl2 along so only newer\nACKs can update the window size.\n\nalso avoids the
    state where snd_wl2\nis eventually larger than th_ack and thus\nblocking the window
    update mechanism and\nthe connection gets stuck for a loooong\ntime in the zero
    sized send window state.\n\nsee PR/kern 55567\n\nok thorpej@, also found in FreeBSD\n"
