Wait for the receive traffic to become idle before attempting to close
or reset the adapter.  To enable the processing of packets while Receive
Idle, move the clearing of __VXGE_STATE_CARD_UP bit in vxge_close to
after it.  Also, modify the return value of the ISR when the adapter is
down to IRQ_HANDLED.  Otherwise there are unhandled interrupts for the
device.

- Removed accessing GENDMA_INT register
 - This allowed the firmware to perform a generic DMA write to host memory.
   This feature is not supported by the ASIC, this patch removes access to
   GENDMA_INT register.

- Complete Register map details of Neterion Inc's X3100 Series 10GbE PCIe I/O
  Virtualized Server Adapter.

- No change from previous submission.

- Changes in previous submissions -
- Incorporated following comments from Ben Hutchings
        - Use original macros for endian checks
        - Remove VXGE_OS_PLATFORM_* macros as they are unused.
        - Converted multiple bVALX macros into single with additional
          width parameter and renamed it to vxge_bVALn.
        - Using __packed instead of pragma pack(1)
        - Added a comment of the use of a hw swapper so driver code is
          portable (does not have to change the byte order for register
          access as well as dma operations) on different ENDIAN platforms.
        - Using the <linux/pci_regs.h> definitions instead of redefing them.
        - Using the PCI capabilities registers in <linux/pci_regs.h>
          instead of redefing them.
