[ofa-general] minimum sw components requirement for driver/opensm in a single unmanaged switch network

[Yicheng Jia]

Hi Folks,

I have a IB network which consists of only a single unmanaged switch, all 
end nodes connecting with the switch only need to do RDMA read/write 
operation with each other. My question is, what are the indispensable 
modules in driver's core and opensm that make the network up and run? 

I've been using only ib_mad module in driver's core with a managed switch 
before, and the network works fine. So I assume that only the ib_mad 
module in driver's core and SM in opensm are mandatory in my network. The 
LIDs are assigned by them. The SA and CM modules are not useful in my 
case. Am I right?

I need to minimize driver and opensm to fit them in my network, the HCA 
driver is mthca.

Best,
Yicheng
