It turns out that the InterruptThrottleRate module parameter was only
having the effect of locking the ITR at the starting ITR value. This was
because the values stored in rx_itr_setting and tx_itr_setting were being
ignored when configuring the initial itr_val of the q_vector.

Jeff Kirsher says:
====================
This series contains updates to ixgbe only.
v2- Dropped the following 2 patches from the series:
ixgbe: Support using build_skb in the case that jumbo frames are disabled
ixgbe: walk pci-e bus to find minimum width
Ben Hutchings found a bug with Alex's patch, so that patch was dropped
permanently. Jacob's "walk PCIe bus" patch is being re-worked for
a more generic solution so that other drivers can benefit.
In the remaining patches...
Alex provides a fix where we were incorrectly checking the entire frag_off
field when we only wanted the fragment offset. Alex also cleans up
the check for PAGE_SIZE, since the default configuration allocates 32K
for all buffers.
Emil provides a change to the calculation of eerd so that it is consistent
between the read and write functions by using | instead of +.
Jacob adds support for displaying PCIe Gen3 link speed, which was
previously missing from the ixgbe driver. He also provides a patch
to clean up ixgbe_get_bus_info_generic to call some conversion
functions, which are used also in another patch provided by Jacob.
Jacob modifies the driver to enable certain devices (which have an
internal switch) to read from the physical slot rather than reading
data from the internal switch.
Don provides a couple of fixes (which are more appropriate for net-next),
one of which resolves an issue where ixgbe was only turning on the laser
when the adapter was up which caused issues for those who wanted to
access the MNG firmware while the port was in a down state. The other
fix is for WoL when currently linked at 1G. Lastly Don bumps the driver
version keep the in-kernel driver up to date with the current functionality.

We reset during the shutdown path which will reset AUTOC register. This
would change LMS to 10G. If we were currently linked at 1G we will lose
link, which is a bad thing if we wanted WoL to work. For the fix I needed
to know if WoL is supported so I created a new bool in the ixgbe_hw struct.
If this is set we will not allow the reset to change the current LMS value
in AUTOC.

The different steering modes are global to the device, with DMFS
being introduced after SRIOV was merged. Hence, SRIOV guests running
legacy / older Linux kernels or non-Linux drivers may provide
B0 steering directives when the hypervisor is using DMFS and fail.
Under B0 only L2 steering rules are allowed, hence B0 is a subset of DMFS.
Use this fact to enable such legacy guests to run by modifying the SRIOV
B0 steering wrapper to translate guest B0 directives to DMFS ones when
the device uses DMFS. The translated B0 rule has to be kept in the
resource tracker as a B0 object to allow for lookup in case of detach.
