The kernel goes BUG() at the time 'ethtool -p eth0 3' comes
back, which is due to adapter->led_blink_task initialized
several times.  At the time it is still running this results
in a corrupted task_list of the associated workqueue.

The fix is to move the workqueue initialization to the
probe function instead.

Based on a patch from Jesse Gross.

Enable vlan tag insertion even when vlan group is not configured.

For ixgb HW both CTRL0.VME and VLE bit in the Tx descriptor need to be set
in order to enable HW acceleration.

Introduced separate functions for enabling/disabling of vlan tag stripping
similar to ixgbe.

When hot-unplugging a vxge adapter while running, the driver's remove
routine prints warning and then stalls the calling thread.  This is due
to vxge_remove calling vxge_device_unregister to unregister the netdev
before calling flush_scheduled_work clear any pending work.  Swapping
the order of these two functions resolves the issue.

Calling pci_disable_sriov when unloading a SR-IOV physical function
driver from a host when a guest is using a virtual function from that
device can cause a host crash or VM crash.  The crash is caused by the
virtual config space no longer being present when PF is removed (due to
the pci_disable_sriov).  This can be avoided by not calling
pci_disable_sriov to disable the PCI space when shutting down the PF.
Each function in the X3100 operates independently and in this case will
operate properly in the absence of the PF.

Also, added improved logic in the detection of SR-IOV initialization.
