      Neterion: New driver: Hardware init & configuration · 40a3a915
      Ramkrishna Vepa authored 
      This patch takes care of Initialization and configuration steps of
Neterion Inc's X3100 Series 10GbE PCIe I/O Virtualized Server Adapter.
- Device Initialization.
- Verification and setting of device config parameters.
- Allocation of Tx FIFO and Rx Ring descriptors (DTR).
- APIs to get various type of hw stats
- APIs to configure RTS (Receive Traffic Steering)

- Changes in this submission -
        - Include vmalloc header without which a compilation error occured
          on sparc64, ppc64 and IA64 plaforms.
	- Fixed compilation warning in register_poll, write32_upper,
          write32_lower and the special write64 functions on ppc64.
        - General cleanup - removed redundant includes and defines.

- Changes in previous submissions -
        - Add readq/writeq implementation for the driver for 32 bit systems -
          reported by Dave Miller.
- Incorporated following comments from Ben Hutchings
        - Start a comment with "/**" to make it a kernel-doc comment.
        - Use prefix, "__vxge" in front of hw functions to make them globally
          unique.
        - Fixed unnecessary clearing members of *channel just before freeing
        - Use backslashes only for macro definitions and not in multi-line
          statements.
        - Used pci_find_capability instead of redefining it.
        - Used device and revision ids that are already in pdev - no need to
          read them again.
        - Used pci_save_state() and pci_restore_state() around resets.
        - Used udelay and mdelay directly instead of wrapper.
        - In __vxge_hw_device_register_poll() reset i to 0 after the
          microsecond delay loop to commence the millisecond delay loop.
        - Corrected spelling "sapper" - should be "swapper"
        - Remove too much vertical whitespace.
        - Replaced magic numbers with appropriate macros
- Incorporated following comments from Andi Kleen [andi@firstfloor.org]
        - Reduced the arguments in functions or refactored them into smaller
        functions.
        - Allocate page sized memories used in slow path with vmalloc.
        - Use asserts where necessary.
        - Use macros instead of magic numbers.
        - Use the pci layer code instead of defining own functions
        - Remove driver wrappers such as xge_hw_device_private_set().
        - Fixed sparse warnings.

      Neterion: New driver: register set - vxge-reg.h · 66d97fed
      Ramkrishna Vepa authored 
      - 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.

      Ramkrishna Vepa authored 
      - vxge driver help text file.

- No change from previous submission.

- Changes in previous submissions -
  Removed the performance tuning section with instructions to disable
  time stamps and change sysctl settings - Reported by Dave Miller
  General clean up.
 - Removed tx/rx_pause, exec_mode, tx_steering_type, rx_steering_type, gro,
   intr_type, rx & tx max_indicate_pkts and exec_mode loadable parameters. The
   driver default settings work well in most if not all cases. Another patch
   to configure these parameters with ethtool will be released in the future -
   Reported by Stephen Hemminger.
- Incorporated following fixes based on comments from Ben Hutchings
        Removed references to earlier kernel versions.
        Removed sections that are similar for all drivers -
                Load/Unload
                Identifying the adapter/interface
                Boot time configuration
        Removed loadable parameter -
                NAPI - Napi is always enabled.
                rx_steering_type & ring_blocks - The driver default settings
                work well in most if not all cases. Another patch to configure
                these parameters with ethtool will be released in the future.
        Removed ethtool support section - No need to duplicate ethtool
                docs here.
        Removed Known Issue on SUSE 9 - Doesn't apply when using a
                current kernel.
        Removed Common Problems section - These don't apply to in-tree modules.
        Removed Available Downloads section - Not sure this belongs in-tree.
        Removed Copyright information - This notice doesn't belong in
                the kernel.
