Jeff Kirsher says:

====================
This series contains updates to ixgbe and pci.

The first patch for ixgbe from Greg Rose is the second submission.  The
first submission of "ixgbe: Retain VLAN filtering in promiscuous + VT
mode" had a typo, which Joe Perches pointed out and is fixed in this
submission.

Alex updates the ixgbe driver to use the generic helper pci_vfs_assigned
instead of the driver specific function ixgbe_vfs_are_assigned.

Don Skidmore provides 4 patches for ixgbe, the first being a fix for
flow control ethtool reporting.  Originally ixgbe_device_supports_autoneg_fc()
was expected to be called by only copper devices, which lead to false
information being displayed via ethtool.  Two other patches add support
for fixed fiber for SFP+ devices and the addition of a quad-port x520
adapter.  The last patch simply bumps the driver version.

Emil Tantilov provides 3 fixes for ixgbe, two of which resolve
semaphore lock issues.  The third fix resolves several issues in the
previous implementation of the SFF data dumps of SFP+ modules.

The remaining ixgbe and pci patches are from Jacob Keller.  The pci
patches exposes bus speed, link speed and bus width so that drivers
can take advantage of this information.  In addition, adds a pci function
which obtains minimum link width and speed.  Jacob also provides the
ixgbe patch to incorporate the pci function. He provides a patch that
fixes a lockdep issue created due to ixgbe_ptp_stop always running
cancel_work_sync even if the work item had not been created properly with
INIT_WORK. This issue was found and reported by Stephen Hemminger.

-v2-
* fix patch 3 to be a bool function based on David Miller's feedback
* fix patch 4 debug message based on David Miller's feedback
* fix patch 8 moved the extern declarations to pci.h based on Bjorn
  Helgaas's feedback
* fix patch 11 update the error message to include encoding loss based
* fix patch 8/9/10 title based on Bjorn's feedback
