Log:
  MFC 353323: Set the FID field in lookaside crypto requests to the rx queue ID.
  
  The PCI block in the adapter requires this field to be set to a valid
  queue ID.  It is not clear why it did not fail on all machines, but
  the effect was that crypto operations reading input data via DMA
  failed with an internal PCI read error on machines with 128G or more
  of RAM.
