Subject: [RFC PATCH 00/11] IB/Verbs: IB Management Helpers


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 is supported by the device/port.

Thus instead of inferring, we should have our own mechanism for
IB management capability/protocol checking, several proposals below.

This patch set is the pioneer which try to collecting all the cases where
a management helper applicable, and put all the speculating logical together,
in order to be easily integrated to the new querying mechanism in future.

TODO:
    The helper in patch 10 and 11 are still to be classified, that is
    cap_ib() and cap_eth().

    The name/description of each helper may not correct enough, those folks
    who are familiar with these particular parts, your suggestion would be
    invaluable ;-)

Proposals:
