- Allow multiple functions with INTA.
- Removed the condition to allow only one vpath with INTA
- Ensure that the alarm bit in titan_mask_all_int register is cleared when
driver exits.

- Added a function to check if FCS stripping is disabled by the firmware, if
it is not disabled fail driver load.
- By default FCS stripping is disabled by the firmware. With this assumption
driver decrements the indicated packet length by 4 bytes(FCS length).
- This patch ensures that FCS stripping is disabled during driver load time.

- 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.

the privileged function: Resubmit#1
- vxge driver was assuming function-0 is always the privilaged function. Now that
restriction has been removed any function can act as a privilaged function.
- This patch modifies the __vxge_hw_device_is_privilaged routine to not assume
function-0 as the privileged function.
- Recreated the patch by incorporating review comments from Dave Miller to
remove double slash in path names.

- Removed ioremap of bar1 address
Driver needs only bar0 address for register access
- Removed references to bar1 and bar2 addresses

- Enabled SRIOV support in the driver.
- Call __vxge_hw_verify_pci_e_info() for the PF only. This function
verifies the negotiated link width and current link speed in the
Link Status Register (offset 12h) which are reserved fields for VFs
as per the SRIOV specification, section 3.5.8.
- Implemented David Miller's comment to remove the #ifdef CONFIG_PCI_IOV as
these intefaces have NOP versions declared when the defintion is not set.

vfree() does its own 'NULL' check, so no need for check before
calling it.

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.
