Subject: [PATCH 1/2] IB/Verbs: Use helpers to refine the checking on transport and link layer
Date: Wed, 25 Mar 2015 12:12:50 +0100	[thread overview]
Message-ID: <55129832.2070707@profitbricks.com> (raw)

There are too many lengthy code to check the transport type of IB device,
or the link layer type of it's port, this patch set try to use some 
helper to
refine and save us some code.

TODO:
     Currently we inferred from the transport type and link layer type 
to identify
     the way of management, it will be better if we can directly get the 
indicator
     from vendor.

     Sean proposed one suggestion:
  https://www.mail-archive.com/linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org/msg23339.html

     It may need a big work to adapt current implementation to utilize
     these flags elegantly.

     Also the performance concern on query_port() need to be addressed, 
may be
     some new callback like query_mgmt() could works.
