Fix the fix ... One of my previous fixes introduced removal of all fsf
requests in zfcp's eh_host_reset_handler. But this must not happen
before qdio queues are shut down. So, I revert the changes of
zfcp_scsi_eh_host_reset_handler.

Some cards need to pause the sequencer before the SBLKCTL register is
touched.  This fixes a PCI related oops seen on powerpc macs with this
card caused by trying to ascertain the bus signalling before beginning
domain validation.
Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

For cards that don't support LVD, checking the SBLKCTL register to
determine the bus singalling doesn't work.  So, check that the card
supports LVD first (AHC_ULTRA2) before checking the register.

See http://www.torque.net/sg/sdebug26.html for more
information on the scsi_debug driver.

ChangeLog:
  - add 'vpd_use_hostno' parameter to allow simulated hosts
    to see the same set of targets (and luns). For testing
    multipath software.
  - add 'fake_rw' parameter to ignore the data in READ and
    WRITE commands
  - add support for log subpages (new in SPC-4)
  - yield appropriate block descriptor for MODE SENSE
    commands (only for pdt=0 (i.e. disks))
  - REQUEST SENSE response no longer shows the stopped
    power condition (SAT changed to agree with SPC-3)

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
be broken for potentially a long time.

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.
