730a8f8777 i40e: Fix for unexpected messaging
This fixes an issue where a previously removed message
has returned.  Changing the message type to dev_dbg
leaves the info, if desired, but takes it out of normal
everyday usage. Also changed call to only provide port
data when its valid and not when its not (delete case).

3fe06f415b i40e: Do not wait for Rx queue disable in DCB reconfig
Just like Tx queues don't wait for Rx queues to be disabled before
DCB has been reconfigured.
Check the queues are disabled only after the DCB configuration has
been applied to the VSI(s) managed by the PF driver.

In case of any timeout issue a PF reset to recover.

31b606d0c4 i40e: Fix led blink capability for 10GBaseT PHY
This patch fixes a problem where the ethtool identify adapter
functionality did not work for some copper PHY's.  Without this
patch, the blink led functionality fails on some parts.  This
patch adds PHY write code to blink led's on parts where this
functionality is contained in the PHY rather than the MAC.

bc5d252b36 i40e: Update feature flags to reflect newly enabled features
Recent changes should have enabled support for IPv6 based tunnels and
support for TSO with outer UDP checksums.  As such we can update the
feature flags to reflect that.

In addition we can clean-up the flags that aren't needed such as SCTP and
RXCSUM since having the bits there doesn't add any value.

84d5946d49 i40e: Do not drop support for IPv6 VXLAN or GENEVE tunnels
All of the documentation in the datasheets for the XL710 do not call out
any reason to exclude support for IPv6 based tunnels.  As such I am
dropping the code that was excluding these tunnel types from having their
port numbers recognized.  This way we can take advantage of things such as
checksum offload for inner headers over IPv6 based VXLAN or GENEVE
tunnels.

a9c9a81f58 i40e/i40evf: Drop outer checksum offload that was not requested
The i40e and i40evf drivers contained code for inserting an outer checksum
on UDP tunnels.  The issue however is that the upper levels of the stack
never requested such an offload and it results in possible errors.

In addition the same logic was being applied to the Rx side where it was
attempting to validate the outer checksum, but the logic there was
incorrect in that it was testing for the resultant sum to be equal to the
header checksum instead of being equal to 0.

Since this code is so massively flawed, and doing things that we didn't ask
for it to do I am just dropping it, and will bring it back later to use as
an offload for SKB_GSO_UDP_TUNNEL_CSUM which can make use of such a
feature.

As far as the Rx feature I am dropping it completely since it would need to
be massively expanded and applied to IPv4 and IPv6 checksums for all parts,
not just the one that supports Tx checksum offload for the outer.

a16ae2d59c i40e: Do not disable queues in the Legacy/MSI Interrupt handler
The queues should never be enabled/disabled in the interrupt handler,
ICR0 interrupt enable should be the only thing that needs to be

This patch fixes that. Without this patch X722 platforms were
seeing weird ping timings when in Legacy mode since it takes

6784ed5a73 i40e: Fix PROMISC mode for Multi-function per port (MFP) devices
This patch falls back to enabling unicast, multicast and
broadcast promiscuous mode when the driver must disable it's use
of "default port" aka defport mode (which is normally used to
provide a promiscuous mode), due to internal incompatibility
with Multiple Function per Port (aka MFP).

The situation that requires this patch is when Physical
Function 0 is the device being used, and it can support SR-IOV
when MFP is enabled, via the driver creating a VEB on an MFP
enabled adapter.

dd353109e4 i40e: Add a SW workaround for lost interrupts
This patch adds a workaround for cases where we might have
interrupts that got lost but WB happened.
If that happens without this patch we will see a tx_timeout.
To work around it, this patch goes ahead and reschedules NAPI
in that situation, if NAPI is not already scheduled.
We also add a counter in ethtool to keep track of when
we detect a case of tx_lost_interrupt.

Note: napi_reschedule() can be safely called from process/service_task
context and is done in other drivers as well without an issue.

40d72a5098 i40e/i40evf: don't lose interrupts
While re-enabling interrupts the driver would clear all pending
causes. This meant that if an interrupt was generated while the driver
was cleaning or polling with interrupts disabled, then that interrupt
was lost.  This could cause a queue to become dead, especially for
receive.  Refactored the enable_icr0 function in order to allow
it to be decided by the caller whether the CLEARPBA (clear pending
events) bit will be set while re-enabling the interrupt.

Also update copyright year in file headers.

8a187f448e i40e: add VEB stat control and remove L2 cloud filter
With the latest firmware, statistics gathering can now be enabled and
disabled in the HW switch, so we need to add a parameter to allow the
driver to set it as desired.  At the same time, the L2 cloud filtering
parameter has been removed as it was never used.

Older drivers working with the newer firmware and newer drivers working
with older firmware will not run into problems with these bits as the
defaults are reasonable and there is no overlap in the bit definitions.
Also, newer drivers will be forced to update because of the change in
function call parameters, a reminder that the functionality exists.

====================
40GbE Intel Wired LAN Driver Updates 2016-02-16

This series contains updates to i40e/i40evf only.

Shannon adds flags to MAC allocation requests to signify that the MAC VLAN
filters should come from the shared resource pool.  Added a new "set switch
config" admin queue command and the new Cisco VXLAN-GPE cloud tunnel type
for the admin queue commands.  Added more detail to the NVM update debug
message in order to see the full ethtool request data.  Also added a few
more bits of netdev data into the debugfs output for dump VSI.

Pandi fixes the width of two datatypes which were being declared a different
size from what they are assigned.

Anjali fixes an issue where we were not doing write-back on interrupt
throttle for legacy case in x722.

Mitch adds a counter for ARQ overflows since sometimes an ever-growing
number indicates that something bad is happening.  Also added 20G speed for
Tx bandwidth calculations.

Jesse refactors the DCB function based on a community suggestion to change
the multi-level if statement into a switch statement.  Cleans up VF device
IDs in the PF, since it does not need to know them.

or potentially even child qdiscs.

1d0a4ada84 i40e: add counter for arq overflows
Sometimes, ARQ overflows are a big deal and tell us that the
firmware/hardware/driver/something is having problems. But normally
they're no big deal. To assist in assessing this, add a counter to
our Ethtool stats. A handful of ARQ overflows during VF init is no
problem. A large, ever-growing number indicates that Something Bad is
happening.

b499ffb0a2 i40e: Look up MAC address in Open Firmware or IDPROM
This is the i40e equivalent of commit c762dff24c06 ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").

As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.

In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.

The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.

a188222b6e net: Rename NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK
The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the
set of features for offloading all checksums. This is a mask of the
checksum offload related features bits. It is incorrect to set both
NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.

This patch:
  - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
    NETIF_F_ALL_CSUM is being used as a mask).
  - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to
    use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.
