The vxge driver will drop a packet in its transmit function if the number
of TxDs available hits 0. Instead of doing that, simply stop the transmit
queue when transmitting a packet with the last available TxD.

PCI drivers that implement the struct pci_error_handlers' error_detected
callback should return PCI_ERS_RESULT_DISCONNECT if the state passed in is
pci_channel_io_perm_failure. This patch fixes the issue for vxge.

- 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).

- Fixes in isr routine
Fixed crash with INTA mode during driver unload. Pass hldev to request_irq
instead of vdev.
Fixed Traffic failure with GRO in INTA mode. Pass the correct napi
context to gro functions.

- Removed the code to bounds check the mss value. The hardware does bounds checking and
will not allow an oversized mss to lockup the transmit path.

This patch is the result of an automatic spatch transformation to convert
all ndo_start_xmit() return values of 0 to NETDEV_TX_OK.
Some occurences are missed by the automatic conversion, those will be
handled in a seperate patch.

- 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.

Followup of commits 9d21493b4b
and 08baf56108
(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.
- LRO has been deprecated in favour of GRO - Bill Fink & Dave Miller's comment
- Fixed sparse warnings - Reported by Andi Kleen
- Removed unused variables
