[openib-general] SMI comments

[Hal Rosenstock]

Hi,

I started looking at the SMI code in detail and have a few
questions/comments below. 

I am assuming the implementation is based on the IBA 1.1 spec
description. 

It looks to me like there is no SMP initialization code (per 14.2.2.1
and 14.2.2.3). 14.2.2.1 doesn't matter right now as we don't initiate
any outgoing SMPs, but 14.2.2.3 does. I think this is why I needed the
hop pointer workaround.

I also didn't see the LID handling as described in this section of the
spec. 

In terms of switches, the port is the input or output (physical) port
and not the port of the MAD registration (base or enhanced port 0).

More detailed comments and one or more patches to follow based on these
comments.

Thanks.
