The only purpose of passing this parameter is to check for
prepare phase. The only reason for a failure in that state is if
TLVs don't fit into descriptor. That is highly unlikely and if that
happens, it is a driver bug. So remove this parameter from

40GbE Intel Wired LAN Driver Updates 2016-02-17

This series contains updates to i40e/i40evf only.

Jesse cleans up a duplicate declaration in probe.  Then fixes a bug where the
driver was using a offset based off a DMA handle while mapping and unmapping
using sync_single_range_for_[cpu|device], when it should be using DMA handle
(returned from alloc_coherent) and the offset of the memory to be sync'd.
Fixed an issue where sync_vsi_filter() was allocating memory in a way that
could sleep (GFP_KERNEL) which was causing a problem when called by the
team driver under rcu_read_lock().

Shannon adds a check to ensure we do not attempt to do TSO when
skb->ip_summed is not set to CHECKSUM_PARTIAL.

Kiran add functions related to port mirroring features such as add/delete
mirror rule.

Jacob assigns the i40e_pf structure directly instead of using a large
memcpy, to avoid a sparse warning and lets the compiler optimize the copy
since it know the size of the structure in advance.

Anjali enables GENEVE capability for XL710/X710 devices with firmware API
version higher than 1.4.  Added flag for automatic rule eviction feature
for X722, which is disabled by default.

amd-xgbe: AMD XGBE driver updates 2016-02-12

The following updates and fixes are included in this driver update series:

- Disable VLAN filtering in promiscuous mode
- Change from using napi_complete to napi_complete_done
- Use __napi_schedule_irqoff when running in interrupt context
- Verify ethtool speed setting is valid for the selected speedset
- Enable PFC based on the pfc_en setting
- Fix the mapping of priorities to traffic classes
- Do traffic class setup when DCB nl callbacks are invoked
- Check Rx queue fifos before stopping Rx queue DMA
- Switch from disable_irq to masking interrupts for auto-negotiation

This patch series is based on net-next.

Changes from v1:
- Removed #ifndef and #define of CRCPOLY_LE as part of the patch to
  disable VLAN filtering in promiscuous mode
- Reworked changes to xgbe_setup_tc to resolve conflicts with commit
  16e5cc64 (net: rework setup_tc ndo op to consume general tc operand)
====================

Currently the auto-negotiation interrupt handling disables the irq
instead of masking off the interrupts. This was done because the phy
library was originally used to read and write the PCS registers, which
could not be performed in interrupt context. Now that the phy library is
no longer used to read and write the PCS registers the interrupts can be
masked off in the interrupt service routine eliminating the need to call
disable_irq/enable_irq. This also requires changing the protection mutex
to a spinlock.

Currently the netdev traffic class setup is only performed when invoked
through the ndo_setup_tc interface. However, the same setup should be
performed when the dcbnl interface (ieee_setets) is invoked. Rework the
netdev traffic class setup to be invokable through either interface and
also provide the priority to traffic class mapping if available.

The driver is checking the pfc_en field of the ieee_pfc structure to
determine whether to associate a priority with a traffic class. This is
incorrect since the pfc_en field is for determining if PFC is enabled
for a traffic class.

The association of priority to traffic class does not depend on whether
the traffic class is enabled for PFC, so remove that check. Also, the
mapping of priorities to traffic classes should be done when configuring
the traffic classes and not the PFC support so move the priority to traffic
class association from xgbe_config_dcb_pfc to xgbe_config_dcb_tc.
