REVISION SUMMARY
  In fact the pointer is used only if more than one TXQ is processed in
  one
  interrupt.
  It is used (read-write) on completion path only.
  Also it makes the first part of the structure smaller and it fits now
  into one 128byte cache line. So, TXQ structure becomes 128 bytes
  smaller.
