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 ;-)
