2bd92cd2a5 be2net: enable IOMMU pass through for be2net
This patch sets the coherent DMA mask to 64-bit after the be2net driver has
been acknowledged that the system is 64-bit DMA capable. The coherent DMA
mask is examined by the Intel IOMMU driver to determine whether to allow
pass through context mapping for all devices. With this patch, the be2net
driver combined with be2net compatible hardware provides comparable
performance to the case where vt-d is disabled. The main use-case for this
change is to decrease the time necessary to copy virtual machine memory
during KVM live migration instantiations.

This patch was tested on a system that enables the IOMMU in non-coherent
mode. Two DMA remapper issues were encountered in the previous version and
both patches have been committed.

Don't log "Out of MCCQ wrbs" msg. When the driver doesn't receive any

The driver runs out of MCCQ wrbs much later. Also, this message can

bb5b052f75 bond: add support to read speed and duplex via ethtool
This patch adds support for the get_settings ethtool op to the bonding
driver.  This was motivated by users who wanted to get the speed of the
bond and compare that against throughput to understand utilization.
The behavior before this patch was added was problematic when computing
line utilization after trying to get link-speed and throughput via SNMP.

Output from ethtool looks like this for a round-robin bond:

Settings for bond0:
	Supported ports: [ ]
	Supported link modes:   Not reported
	Supported pause frame use: No
	Supports auto-negotiation: No
	Advertised link modes:  Not reported
	Advertised pause frame use: No
	Advertised auto-negotiation: No
	Speed: 11000Mb/s
	Duplex: Full
	Port: Other
	PHYAD: 0
	Transceiver: internal
	Auto-negotiation: off
	MDI-X: Unknown
	Link detected: yes

I tested this and verified it works as expected.  A test was also done
on a version backported to an older kernel and it worked well there.

v2: Switch to using ethtool_cmd_speed_set to set speed, added check to
SLAVE_IS_OK for each slave in bond, dropped mode-specific calculations
as they were not needed, and set port type to 'Other.'

v3: Fix useless assignment and checkpatch warning.

c1cb0d3b56 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next
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.

b8f8363895 ixgbe: Fix 1G link WoL
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.

0b2679d61c ixgbe: fix MNG FW support when adapter not up
We were only turning the laser on when the adapter was up.  This
causes issues for those who wanted to access the MNG FW while the
port was in a down state.  This patch makes sure the laser is turned
on in probe and remain up even after the port is brought down.

b8e820015e ixgbe: enable devices with internal switch to read pci parent
This patch modifies the driver to enable certain devices, which have an internal
switch, to read data from the physical slot rather than reading data from the
internal switch. The internal switch will always report the same PCI width and
speed, which is not useful compared to knowing the width and speed of the slot
the physical card is plugged into.

7f66162b62 ixgbe: Drop check for PAGE_SIZE from ixgbe_xmit_frame_ring
The check for PAGE_SIZE is pointless now that the default configuration is to
allocate 32K for all buffers.  Since the Tx descriptor limit is 16K we can
just drop the check and always compare the descriptors to the maximum size
supported.
