This patch replaces dev->mc_count in all drivers (hopefully I didn't miss
anything). Used spatch and did small tweaks and conding style changes when
it was suitable.

- 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.

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.

This patch prefetches RxD descriptors which helps to lower the latency of a
cache miss in vxge_hw_ring_rxd_next_completed. This lowers the % of CPU
time used by vxge_hw_ring_rxd_next_completed() where the descriptor is
accessed in profiling netperf on a P4 Xeon from 1.5% to 1.0%.

This patch fixes a case in the transmit completion code which was resulting
in pktgen hanging at the end of a run. The cause is due to the fact that
the ->cb[] area of an skb cannot be used in a network driver's transmit
path, as that area belongs to the network protocol. Pktgen hangs, as it
sends out the same packet multiple times, and vxge's use of this area of
the skb for a temporary list can only add the packet to the temporary list
once (while it may be on the queue many times). The fix is to remove this
abuse of skb->cb[]. Instead, skb pointers are placed into a temporary
stack array, and then free outside of the tx lock. This retains the smp
optimization of doing dev_kfree_skb() outside of the tx lock.

- Disable fcs stripping. The minimum frame size that can be received by the
hardware is 57 Bytes. A 64 Byte Ethernet frame with the vlan tag and fcs
stripped will result in a 56 Byte frame which will lock up the receive
engine. The work around is to disable fcs stripping in the hardware which
is done with a firmware upgrade. The fixes are -
1. Ensure that the correct firmware version is used.
2. Decrement the indicated packet length of the receive packet by 4 bytes
(FCS length).

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.

these intefaces have NOP versions declared when the defintion is not set.

(net: tx scalability works : trans_start)
(net: txq_trans_update() helper)
Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Multi queue drivers can
avoid one cache miss (on dev->trans_start) in their start_xmit()
handler.
Exceptions are NETIF_F_LLTX drivers (vxge & tehuti)

This patch implements all the driver entry point functions.
- Definition of all module loadable paramters.
- Implementation of all driver entry point functions.
- Changes in this submission -
- Fixed compilation error when enabling debug statements
- Fixed few warnings when CONFIG_PCI_MSI is not defined
- Removed unnecessary volatile variables
- Removed compare_ether_addr as it causes unaligned memory access on
the sparc64 platform.
- Changes in previous submissions -
- As per Stephen Hemminger's comments removed the following loadable
parameters - gro, rx_& tx max_indicate_pkts, exec_mode, rx & tx
pause_enable, tx_steering_type and intr_type.
- Added Device ID definition in vxge-main.h instead of
include/linux/pci_ids.h file - Reported by David Miller
- Incorporated following review comments from Ben Hutchings
- NAPI is always enabled (no option to turn it OFF).
- Loadable parameters
rx_steering_type: This loadable option is removed.
ring_blocks: This loadable option is removed.
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.

- Fixed sparse warnings - Reported by Andi Kleen
