Re: [myrinet] Re: Re: Fast Directed Writes

GM orders packets between nodes (i.e. NICs) using go-back-N.  So if a
packet is received that has a sequence number other than the expected one,
it is dropped.  Of course this is only true of "reliable" and "directed"
packets (not datagram, or ethernet (I think)).
