[SCSI] lpfc: Fix for "Unknown IOCB command Data: x0 x3 x0 x0"
Fix for "Unknown IOCB command Data: x0 x3 x0 x0" messages and inability to see devices On some platforms, the host-memory based ring mgmt area was not zero. Also, driver wasn't manipulating the entire 32bits of the ring pointers. Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
