Re: Fwd: Re: [openib-general] static LID computationwithTS_HOST_DRIVER

The port may put any value in the LID during its initialization (an time 
before it starts responding to SMPs).  However, there is nothing in the 
specification that says that the SM should use it.  I sent another email 
with a more compete description.

Right, as I said before, that's what I thought (but I wasn't sure I
hadn't missed something).  So the IBA doesn't make any statement about
what value PortInfo:LID should be initialized to.  Presumably the IBA
doesn't require that PortInfo:LID be initialized to a random value
contained in an uninitialized memory location, so I don't see a
problem with the SMA initializing PortInfo:LID to an algorithmicly
determined value as part of boot-up.  And, unlike the P_Key table, the
IBA makes no statement about this initialization algorithm.
