When ipoib_ib_dev_flush() is called because of a port event, the
driver needs to rejoin all multicast groups, since the flush will call
ipoib_mcast_dev_flush() (via ipoib_ib_dev_down()).  Otherwise no
(non-broadcast) multicast groups will be rejoined until the networking
core calls ->set_multicast_list again, and so multicast reception will

IPoIB: Create MCGs with all attributes required by RFC

RFC 4391 ("Transmission of IP over InfiniBand (IPoIB)") says:

  If the IB multicast group does not already exist, one must be
  created first with the IPoIB link MTU.  The MGID MUST use the same
  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
particular the MTU and HopLimit are not being set.  Add these
attributes when creating MCGs, and also set the Rate attribute, since
IPoIB pays attention to that attribute as well.

As iser is able to use at most one rdma operation for the
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.

and to take that into account when processing the sg.

Sean Hefty [Mon, 28 Aug 2006 22:10:32 +0000]
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.

The SM LID used to send traps to is incorrectly set to port LID.  This
is a regression from 2.6.17 -- after a PortInfo MAD is received, no
traps are sent to the SM LID.  The traps go to the loopback interface
instead, and are dropped there.  The SM LID should be taken from the
sm_lid of the PortInfo response.

The bug was introduced by commit 12bbb2b7be7f5564952ebe0196623e97464b8ac5:

ioremap balanced with iounmap for drivers/mtd subsystem

ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.

Tested (compilation only) with:
- allmodconfig
- Modifying drivers/mtd/maps/Kconfig and drivers/mtd/nand/Kconfig to
make sure that the changed file is compiling without warning
