If the IB multicast group does not already exist, one must be

P_Key, Q_Key, SL, MTU, and HopLimit as those used in the
broadcast-GID. The rest of attributes SHOULD follow the values used
in the broadcast-GID as well.
However, the current IPoIB driver is only setting the attributes
required by the InfiniBand spec to create a multicast group, so in

attributes when creating MCGs, and also set the Rate attribute, since

execution of a scsi command, and registration of the sg
associated with scsi command has its restrictions, the code
checks if an sg is "aligned for rdma".
Alignment for rdma is measured in "fmr page" units whose
possible resolutions are different between HCAs and can be
smaller, equal or bigger to the system page size.
When the system page size is bigger than 4KB (eg the default
with ia64 kernels) there a bigger chance that an sg would be
aligned for rdma if the fmr page size is 4KB.
Change the code to create FMR whose pages are of size 4KB
and to take that into account when processing the sg.

IB/mad: Add support for dual-sided RMPP transfers.
The implementation assumes that any RMPP request that requires a
response uses DS RMPP. Based on the RMPP start-up scenarios defined
by the spec, this should be a valid assumption. That is, there is no
start-up scenario defined where an RMPP request is followed by a
non-RMPP response. By having this assumption we avoid any API
changes.
In order for a node that supports DS RMPP to communicate with one that
does not, RMPP responses assume a new window size of 1 if a DS ACK has
not been received. (By DS ACK, I'm referring to the turn-around ACK
after the final ACK of the request.) This is a slight spec deviation,
but is necessary to allow communication with nodes that do not
generate the DS ACK. It also handles the case when a response is sent
after the request state has been discarded.
