Protect the code by bailing out of ixgbe_update_itr() when this occurs.
The next call to ixgbe_update_itr will continue to dynamically update ITR.

The variable wol_supported really is just checking whether it is enabled, rather
than whether it is supported. If it is enabled it will be supported, but this
does not necessarily hold true the other way around. This patch renames the
variable to avoid confusion.

From: Don Skidmore <donald.c.skidmore@intel.com>
This patch adds LX support to 82599 devices. This is an alternate patch to
the one suggested by Stefan Behte <s.behte@babiel.com>
In addition this patch includes some cleanups such as:
- removed parenthesis around "x == y ||" lines inside an if statement for
consistency.
- grouped the sx/lx sfp types along with srlr in ixgbe_get_settings() since
they all have the same supported, advertised and port values.

It was previously thought that, since I210/I211 are single port devices,
they did not need the SMBI semaphore. This is not the case. Add support for
the SMBI semaphore.

This function is meant to add a helper function that will determine if a PF
has any VFs that are currently assigned to a guest. We currently have been
implementing this function per driver, and going forward I would like to avoid
that by making this function generic and using this helper.
v2: Removed extern from declaration of pci_vfs_assigned in pci.h and return
0 if SR-IOV is disabled which is inline with other PCI SRIOV functions.

Current igb driver doesn't tell nothing when Link Speed is downgraded due to
SmartSpeed. As a result, users suspect that there is something wrong with
NIC. If the cause of it is SmartSpeed, there is no means to replace NIC. This
patch make igb notify users that SmartSpeed worked.

From: Greg Rose <gregory.v.rose@intel.com>
When using the new bridge FDB interface to allow SR-IOV virtual function
network devices to communicate with SW bridged network devices the
physical function is placed into promiscuous mode and hardware VLAN
filtering is disabled. This defeats the ability to use VLAN tagging
to isolate user networks. When the device is in promiscuous mode and
VT mode simultaneously ensure that VLAN hardware filtering remains
enabled.

The 82575 manual initialization scripts are not supported on 82580 and
above. Rather than call the function to immediately return, clarify the
code by removing this pointless function call.

This patch removes id defines from the hardware files that will not be
productized for Linux. These id's were not implemented for support in the
base driver itself, they were just available defines.

Pulled, thanks for getting the PCI review resolved.
