[PATCH v3 00/28] IB/Verbs: IB Management Helpers

[Michael Wang <yun.wang@profitbricks.com>]

Since v2:
  * Apply suggestions from Doug, Ira, Jason, Tom, Steve, thanks for the comments :-)
    and please remind me if I missed anything :-P

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 management
capability/protocol/feature checking, several proposals below.

This patch set will reform the method of getting transport type, we will
now using query_transport() instead of inferring from transport and link
layer respectively, also we defined the new transport type to make the
concept more reasonable.

Mapping List:
		node-type	link-layer	old-transport	new-transport
nes		RNIC		ETH		IWARP		IWARP
amso1100	RNIC		ETH		IWARP		IWARP
cxgb3   	RNIC		ETH		IWARP		IWARP
cxgb4   	RNIC		ETH		IWARP		IWARP
usnic   	USNIC_UDP	ETH		USNIC_UDP	USNIC_UDP
ocrdma  	IB_CA		ETH		IB		IBOE
mlx4    	IB_CA		IB/ETH		IB		IB/IBOE
mlx5    	IB_CA		IB		IB		IB
ehca    	IB_CA		IB		IB		IB
ipath   	IB_CA		IB		IB		IB
mthca   	IB_CA		IB		IB		IB
qib     	IB_CA		IB		IB		IB

For example:
	if (transport == IB) && (link-layer == ETH)
will now become:
	if (query_transport() == IBOE)

Thus we will be able to get rid of the respective transport and link-layer
checking, and it will help us to add new protocol/Technology (like OPA) more
easier, also with the introduced management helpers, IB management logical
will be more clear and easier for extending.

Highlights:
    The patch set covered a wide range of IB stuff, thus for those who are
    familiar with the particular part, your suggestion would be invaluable ;-)

    Patches haven't been tested yet, we appreciate if any one who have these
    HW willing to provide his Tested-by :-)

    Doug suggested the bitmask mechanism:
	https://www.mail-archive.com/linux-rdma@vger.kernel.org/msg23765.html
    which could be the plan for future reforming, we prefer that to be another
    series which focus on semantic and performance.

    This patch-set is somewhat 'bloated' now and it may be a good timing for
    staging, I'd like to suggest we focus on improving existed helpers and push
    all the further reforms into next series ;-)
