[PATCH rdma-next v4 0/8] Add OPA extended LID support

[Don Hiatt <don.hiatt-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

This patch series primarily increases sizes of variables that hold
lid values from 16 to 32 bits. Additionally, it adds a check in
the IB mad stack to verify a properly formatted MAD when OPA
extended LIDs are used.

Changes from v3:
---------------
* Add 'IB/core: Add functions to convert 32 bit lids to 16 bits' and
  use them in place of casts.

Changes from v2:
---------------
* Remove 'IB/mad: Ensure DR MADs are correctly specified when using
  OPA devices' as this will be handled in a lower layer.

Changes from v1:
---------------
* Remove extraneous slid set. 
* Replace slid casts with helper function.
* Return default subnet prefix on rdma_ah_conv_opa_to_ib() failure.

The patches are origanized as follows:

* Patch 1 converts an OPA ah_attr to an IB ah_attr when
  copying from kernel to user. Since OPA ah_attr is only defined
  in the kernel, the function takes care of adding OPA GIDs
  that contain the extended LID before copying to user.
* Patch 2 increases the lid and sm_lid variables in srpt
  to 32 bits.
* Patch 3 increases the local_lid variable in IPoIB to 32
  bits.
* Patch 4 increases the slid variable in MAD RMPP to 32 bits.
* Patch 5 Adds functions to convert 32 bit lids to 16 bits.
* Patch 6 increases the lid field in struct ib_port_attr from
  16 to 32 bits.
* Patch 7 increases the sm_lid field in struct ib_port_attr
  from 16 to 32 bits.
* Patch 8 increases the slid field in struct ib_wc from 16
  to 32 bits.
