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

[David M. Brean]

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.
