119 The QLogic HBA cards all contain a tiny 16-bit RISC-like processor and
126 register, that is a write to an (incoming, to the HBA) mailbox register,
127 while a read to the same address reads another (outgoing, to the HBA)
128 mailbox register with completely different data. Each HBA also then has

165 The QLogic HBA is an interrupting card, and when servicing an interrupt
