Intel Wired LAN Driver Updates 2016-06-29

This series contains updates and fixes to e1000e, igb, ixgbe and fm10k.  A
true smorgasbord of changes.

Jake cleans up some obscurity by not using the BIT() macro on bitshift
operation and also fixed the calculated index when looping through the
indir array.  Fixes the issue with igb's workqueue item for overflow
check from causing a surprise remove event.  The ptp_flags variable is
added to simplify the work of writing several complex MAC type checks
in the PTP code while fixing the workqueue.

Alex Duyck fixes the receive buffers alignment which should not be L1
cache aligned, but to 512 bytes instead.

Denys Vlasenko prevents a division by zero which was reported under
VMWare for e1000e.

Amritha fixes an issue where filters in a child hash table must be
cleared from the hardware before delete the filter links in ixgbe.

Bhaktipriya Shridhar simply replaces the deprecated create_workqueue()
with alloc_workqueue() for fm10k.

Tony corrects ixgbe ethtool reporting to show x550 supports hardware
timestamping of all packets.

Emil fixes an issue where MAC-VLANs on the VF fail to pass traffic due
to spoofed packets.

Andrew Lunn increases performance on some systems where syncing a buffer
for DMA is expensive.  So rather than sync the whole 2K receive buffer,
only synchronize the length of the frame.

Andrew Lunn 64f2525ca4 igb: Only DMA sync frame length
On some platforms, syncing a buffer for DMA is expensive. Rather than
sync the whole 2K receive buffer, only synchronise the length of the
frame, which will typically be the MTU, or a much smaller TCP ACK.

For an IMX6Q, this gives around 6% increased TCP receive performance,
which is cache operations bound and reduces CPU load for TCP transmit.

Bhaktipriya Shridhar 0a38c17a21 fm10k: Remove create_workqueue
alloc_workqueue replaces deprecated create_workqueue().

A dedicated workqueue has been used since the workitem (viz
fm10k_service_task, which manages and runs other subtasks) is involved in
normal device operation and requires forward progress under memory
pressure.

create_workqueue has been replaced with alloc_workqueue with max_active
as 0 since there is no need for throttling the number of active work
items.

Since network devices may be used in memory reclaim path,
WQ_MEM_RECLAIM has been set to guarantee forward progress.

flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty. Hence the call to flush_workqueue() has been dropped.

Jacob Keller 8646f7b4cd igb: call igb_ptp_suspend during suspend/resume cycle
Properly stop the extra workqueue items and ensure that we resume
cleanly. This is better than using igb_ptp_init and igb_ptp_stop since
these functions destroy the PHC device, which will cause other problems
if we do so. Since igb_ptp_reset now re-schedules the work-queue item we
don't need an equivalent igb_ptp_resume in the resume workflow.

Denys Vlasenko 3d05b15b03 e1000e: prevent division by zero if TIMINCA is zero
Users report that under VMWare, er32(TIMINCA) returns zero.
This causes division by zero at init time as follows:

 ==>       incvalue = er32(TIMINCA) & E1000_TIMINCA_INCVALUE_MASK;
           for (i = 0; i < E1000_MAX_82574_SYSTIM_REREADS; i++) {
                   /* latch SYSTIMH on read of SYSTIML */
                   systim_next = (cycle_t)er32(SYSTIML);
                   systim_next |= (cycle_t)er32(SYSTIMH) << 32;

                   time_delta = systim_next - systim;
                   temp = time_delta;
 ====>             rem = do_div(temp, incvalue);

This change makes kernel survive this, and users report that
NIC does work after this change.

Since on real hardware incvalue is never zero, this should not affect
real hardware use case.

Jarod Wilson 889ad45666 e1000e: keep VLAN interfaces functional after rxvlan off
I've got a bug report about an e1000e interface, where a VLAN interface is
set up on top of it:

$ ip link add link ens1f0 name ens1f0.99 type vlan id 99
$ ip link set ens1f0 up
$ ip link set ens1f0.99 up
$ ip addr add 192.168.99.92 dev ens1f0.99

At this point, I can ping another host on vlan 99, ip 192.168.99.91.
However, if I do the following:

$ ethtool -K ens1f0 rxvlan off

Then no traffic passes on ens1f0.99. It comes back if I toggle rxvlan on
again. I'm not sure if this is actually intended behavior, or if there's a
lack of software VLAN stripping fallback, or what, but things continue to
work if I simply don't call e1000e_vlan_strip_disable() if there are
active VLANs (plagiarizing a function from the e1000 driver here) on the
interface.

Also slipped a related-ish fix to the kerneldoc text for
e1000e_vlan_strip_disable here...

Greg Rose b33d3b7321 i40e: Clean up MSIX IRQs before suspend
The i40e_suspend() function calls another function that preps the device
for the power save and resume by freeing all the Tx/Rx resources and
interrupts but that function does not free the "other" causes interrupt
vector and IRQ. It also fails to call synchronize_irq() before freeing
the IRQ vectors.  This sometimes may result in some AER errors on those
systems with that PCIe error reporting feature enabled.

Call synchronize_irq() before freeing IRQ vectors and explicitly free
the other causes interrupt resources and shut down that MSIX interrupt.

Mitch Williams 0e8d95f896 i40evf: don't overflow buffer
If the user adds an obscene amount of MAC addresses, the driver will run
into the situation where it has too many address requests to fit into a
single PF message. The driver checks for this case, and calculates the
maximum number of messages that it can send. Then it completely ignores
this count and overflows the buffer.

Fix this by checking the address count and bailing out of the loop at
the appropriate time.

We were failing to set the client interface down when we put the VSI
down. Add this call so that the client doesn't get an open called with
no close.

Also remove an un-needed delay. The VF should not be affected at all by

Alexander Duyck b3a49557d5 ixgbe: Replace ndo_add/del_vxlan_port with ndo_add/del_udp_enc_port
This change replaces the network device operations for adding or removing a
VXLAN port with operations that are more generically defined to be used for
any UDP offload port but provide a type.  As such by just adding a line to
verify that the offload type is VXLAN we can maintain the same
functionality.

In addition I updated the socket address family check so that instead of
excluding IPv6 we instead abort of type is not IPv4.  This makes much more
sense as we should only be supporting IPv4 outer addresses on this
hardware.

The last change is that I pulled the rtnl_lock/unlock into the conditional
statement for IXGBE_FLAG2_VXLAN_REREG_NEEDED.  The motivation behind this
is to avoid unneeded bouncing of the mutex which will just slow down the
handling of this call anyway.

Tom Herbert 7e13318daa net: define gso types for IPx over IPv4 and IPv6
This patch defines two new GSO definitions SKB_GSO_IPXIP4 and
SKB_GSO_IPXIP6 along with corresponding NETIF_F_GSO_IPXIP4 and
NETIF_F_GSO_IPXIP6. These are used to described IP in IP
tunnel and what the outer protocol is. The inner protocol
can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and
SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT
are removed (these are both instances of SKB_GSO_IPXIP4).
SKB_GSO_IPXIP6 will be used when support for GSO with IP
encapsulation over IPv6 is added.

Alexander Duyck 5eee87cd51 ixgbe: Fix VLAN features error
It looks like at some point I somehow transposed the location of setting
the VLAN features in netdev->features and the configuration of the
vlan_features.  As a result the driver is now generating a warning about
vlan_features being setup incorrectly.

This patch corrects that by placing the update of netdev->features to
include the VLAN features so that it is after the point where we write
netdev->features into netdev->vlan_features.
