> Since v4:

> Roland, Ira and Steve :-) Please remind me if anything missed :-P
> * Fix logical issue inside 3#, 14#
> * Refine 3#, 4#, 5# with label 'free'
> * Rework 10# to stop using port 1 when port already assigned

> There are plenty of lengthy code to check the transport type of IB device, or the
> link layer type of it's port, but actually we are just speculating whether a
> particular management/feature is supported by the device/port.
>
> Thus instead of inferring, we should have our own mechanism for IB

> For example:

> Thus we will be able to get rid of the respective transport and link-layer

> The patch set covered a wide range of IB stuff, thus for those who are

> Patch 1#~15# included all the logical reform, 16#~25# introduced the
