Not possible to use XIO_SGL_TYPE_IOV

[Christian Tinnefeld]

 If I send a XIO_SGL_TYPE_IOV I noticed that in my code the sgl_type on the receiving side is always (casted?) to XIO_SGL_TYPE_IOV_PTR (which results in a drop of everything in the iov list but the first element). Then I thought that I’ve done something stupid in my code, so I debugged through the Accelio example code and I’ve found exactly the same problem (I tried with rdma and tcp, see attached screenshots: you can see that in the example the sgltype in the code of the sending guy is XIO_SGL__TYPE__IOV but the receiver sees a XIO_SGL_TYPE_IOV_PTR.

I did extensive testing and here are my findings:
I added a second field by using data_iov and it was not received (using RDMA and Accelio example code) -> see attached accelio-rdma-data_iov.jpg
I added a second field by using pdata_iov and it was not received (using RDMA and Accelio example code) ->see attached accelio-rdma-pdata_iov.jpg
