svn commit: r340468 - head/sys/dev/cxgbe

New Revision: 340468

Log:
  Change the quantum for TLS key addresses to 32 bytes.
  
  The addresses passed when reading and writing keys are always shifted
  right by 5 as the memory locations are addressed in 32-byte chunks, so
  the quantum needs to be 32, not 8.
