/* * Tigon 2 general communication registers. These are 64 and 32 bit * registers which are only valid after the firmware has been * loaded and started. They actually exist in NIC memory but are * mapped into the host memory via the shared memory region. * * The NIC internally maps these registers starting at address 0, * so to determine the NIC address of any of these registers, we * subtract 0x600 (the address of the first register). */
