__bcmgenet_tx_reclaim() is currently summing TX bytes/packets in a way
that is not SMP friendly, mutliples CPUs could run
__bcmgenet_tx_reclaim() independently and still update stats->tx_bytes
and stats->tx_packets, cloberring the other CPUs statistics.
Fix this by tracking per RX and TX rings the number of bytes, packets,
dropped and errors statistics, and provide a bcmgenet_get_stats()
function which aggregates everything and returns a consistent output.

Jeff Kirsher says:
====================
40GbE Intel Wired LAN Driver Updates 2017-03-20
This series contains updates to i40e and i40evf only.
Philippe Reynes updates i40e and i40evf to use the new ethtool API for
{get|set}_link_ksettings.
Jake provides the remaining patches in the series, starting with a fix
for i40e where the firmware expected the port numbers for the offloaded
UDP tunnels in Little Endian format and we were sending them in Big Endian
format which put the wrong port number to be put in the UDP tunnel list.
Changed the driver to use __be32 values instead of arrays for
(src|dst)_ip. Refactored the exit flow of i40e_add_fdir_ethtool() which
removes the dependency on having a non-zero return value. Fixed a memory
leak by running kfree() and returning immediately when we fail to add
flow director filter. Fixed a potential issue where could update the
filter count without actually succeeding in adding a filter, by moving
the ATR exit check to after we have sent the TCP/IPv4 filter to the ring
successfully. Ensures that the fd_tcp_rule count is reset to 0, before
we reprogram the filters so that we do not end up with a stale count
which does not correctly reflect the number of programmed filters. Added
a check whether we have TCP/IPv4 filters before re-enabling ATR after
flushing and replaying FDIR filters. Added counters for each filter
type in preparation for adding code to properly check the mask value.
Fixed potential issues by explicitly checking the flow type at the
start of i40e_add_fdir_ethtool(). To avoid possible memory leaks,
we now unconditionally delete the old filter, even if it is identical to
the new filter and ensures will always update the filters as expected.

The previous code relied on i40e_match_fdir_input_set to determine when
determining whether to free the old filter. Change this code so that we
simply unconditionally delete the old filter, even if it's identical to
the new filter. This ensures that we don't leak any memory, and that we
always update the filters as expected.

Although we will fail the filter later due to checking flow_type which
will have a bogus invalid type, it is possible future refactoring will
remove this hidden failure case. Avoid a possible issue in the future by
explicitly checking the flow type at the start.

In preparation for adding code to properly check the mask values, we
will need to know the number of active filters for each type. Add
counters for each filter type. Rename the already existing fd_tcp_rule
to fd_tcp4_filter_cnt to match the style of other names. To avoid style
warnings, avoid assigning multiple parameters at once, and fix up one
other case where we did so previously.

When flushing and replaying FDIR filters, it is possible we would
disable ATR, and then re-enable it even though we should have kept
it disabled due to existing TCP/IPv4 filters. Fix this by checking
whether we have TCP4/IPv4 filters before re-enabling.
Alternatively, we could instead restore ATR and then replay filters,
however, this would cause us to rapidly enable and then disable ATR in
some cases.

Move ATR exit check after we have sent the TCP/IPv4 filter to the ring
successfully. This avoids an issue where we potentially update the
filter count without actually succeeding in adding the filter. Now, we
only increment the fd_tcp_rule after we've succeeded. Additionally, we
will re-enable ATR mode only after deletion of the filter is actually
posted to the FDIR ring.

Instead of setting err=true and checking this to determine when to free
the raw_packet near the end of the function, simply kfree and return
immediately. The resulting code is a bit cleaner and has one less
variable. This also resolves a subtle bug in the ipv4 case which could
fail to add the first filter and then never free the memory, resulting
in a small memory leak.

The code originally included src_ip and dst_ip with enough space to
support ipv6 filters. However, no actual support for ipv6 filters has
been implemented. Thus, remove the arrays and just use __be32 values.
Should ipv6 support be added in the future, we can replace these with
a union that has sizes for both values.

The firmware expects the port numbers for offloaded UDP tunnels in
Little Endian format. We accidentally sent the value in Big Endian
format which obviously will cause the wrong port number to be put into
the UDP tunnels list. This results in VxLAN and Geneve tunnel Rx
offloads being essentially disabled, unless the port number happens to
be identical after byte swapping. Note that i40e_aq_add_udp_tunnel()
will byteswap the parameter from host order into Little Endian so we
don't need worry about passing strictly a __le16 value to the command.
This patch essentially reverts b3f5c7bc88ba ("i40e: Fix for extra byte
swap in tunnel setup", 2016-08-24), but in a way that makes the result
much more clear to the reader.

This patch adds support for using 3K buffers in order 1 pages the same way
we were using 2K buffers in 4K pages. We are reserving 1K of room for now
to have space available for future headroom and tailroom when we enable
build_skb support.
One side effect of this patch is that we can end up using a larger buffer
if jumbo frames is enabled. The impact shouldn't be too great, but it
could hurt small packet performance for UDP workloads if jumbo frames is
enabled as the truesize of frames will be larger.

Since there are potential drawbacks to the new Rx allocation approach I
thought it best to add a "chicken bit" so that we can turn the feature off
if in the event that a problem is found.
It also provides a means of validating the legacy Rx path in the event that
we are forced to fall back. At some point in the future when we are
convinced we don't need it anymore we might be able to drop the legacy-rx
flag.

In the case of the Tx rings we need to only clear the Tx buffer_info when
we are resetting the rings. Ideally we do this when we configure the ring
to bring it back up instead of when we are taking it down in order to avoid
dirtying pages we don't need to.
In addition we don't need to clear the Tx descriptor ring since we will
fully repopulate it when we begin transmitting frames and next_to_watch can
be cleared to prevent the ring from being cleaned beyond that point instead
of needing to touch anything in the Tx descriptor ring.
Finally with these changes we can avoid having to reset the skb member of
the Tx buffer_info structure in the cleanup path since the skb will always
be associated with the first buffer which has next_to_watch set.

This change makes it so that instead of going through the entire ring on Rx
cleanup we only go through the region that was designated to be cleaned up
and stop when we reach the region where new allocations should start.
In addition we can avoid having to perform a memset on the Rx buffer_info
structures until we are about to start using the ring again. By deferring
this we can avoid dirtying the cache any more than we have to which can
help to improve the time needed to bring the interface down and then back
up again in a reset or suspend/resume cycle.

This change makes it so that we use the length of the packet instead of the
DD status bit to determine if a new descriptor is ready to be processed.
The obvious advantage is that it cuts down on reads as we don't really even
need the DD bit if going from a 0 to a non-zero value on size is enough to
inform us that the packet has been completed.
In addition I have updated the code so that we only reset the Rx descriptor
length for descriptor zero when resetting a ring instead of having to do a
memset with 0 over the entire ring. By doing this we can save some time on
initialization.

The sunvnet netdev is connected to the controlling ldom's vswitch
for network bridging. However, for higher performance between ldoms,
there also is a channel between each client ldom. These connections are
represented in the sunvnet driver by a queue for each ldom. The driver
uses select_queue to tell the stack which queue to use by tracking the mac
addresses on the other end of each port. When a connected ldom shuts down,
the driver receives an LDC_EVENT_RESET and the port is removed from the
driver, thus a queue with no ldom on the other end will never be selected
for Tx.
The driver was trying to reinforce the "don't use this queue" notion with
netif_tx_stop_queue() and netif_tx_wake_queue(), which really should only
be used to signal a Tx queue is full (aka XOFF). This misuse of queue
state resulted in NETDEV WATCHDOG messages and lots of unnecessary calls
into the driver's tx_timeout handler. Simply removing these takes care
of the problem.

In this driver, there is a "port" created for the connection to each of

individual queue/port stats. This patch breaks out the traffic counts
for the individual ports and gives us a little view into the state of

When an ldom VM is bound, the network vswitch infrastructure is set up for
it, but was being forced 'UP' by the userland switch configuration script.
When 'UP' but not actually connected to a running VM, the ipv6 neighbor
probes fail (not a horrible thing) and start cluttering up the kernel logs.
Funny thing: these are debug messages that never actually show up, but
we do see the net_ratelimited messages that say N callbacks were
suppressed.
This patch defers the netif_carrier_on() until an actual link has been
established with the VM, as indicated by receiving an LDC_EVENT_UP from
the underlying LDC protocol. Similarly, we take the link down when we
see the LDC_EVENT_RESET. Now when we see the ndo_open(), we reset the
link to get things talking again.

All IRQs owned by the PF and VF drivers share the same nondescript name
"octeon"; this makes it difficult to setup interrupt affinity.
Change the IRQ names to reflect their specific purpose:
LiquidIO<id>-<func>-<type>-<queue pair num>
Examples:
LiquidIO0-pf0-rxtx-3
LiquidIO1-vf1-rxtx-0
LiquidIO0-pf0-aux
We cannot use netdev->name for naming the IRQs because:
1. Early during init, the PF and VF drivers require interrupts to
send/receive control data from the NIC firmware; so the PF and VF
must request IRQs long before the netdev struct is registered.
2. The IRQ name can only be specified at the time it is requested.
It cannot be changed after that.

Some Hypervisors detach VFs from VMs by instantly causing an FLR event
to be generated for a VF.
In the mlx4 case, this will cause that VF's comm channel to be disabled
before the VM has an opportunity to invoke the VF device's "shutdown"
method.
For such Hypervisors, there is a race condition between the VF's
shutdown method and its internal-error detection/reset thread.
The internal-error detection/reset thread (which runs every 5 seconds) also
detects a disabled comm channel. If the internal-error detection/reset
flow wins the race, we still get delays (while that flow tries repeatedly
to detect comm-channel recovery).
The cited commit fixed the command timeout problem when the
internal-error detection/reset flow loses the race.
This commit avoids the unneeded delays when the internal-error
detection/reset flow wins.

Now that port netdevs can be enslaved to a VRF master we need to make
sure the device's routing tables won't be flushed upon the insertion of
a l3mdev rule.
Note that we assume the notified l3mdev rule is a simple rule as used by
the VRF master. We don't check for the presence of other selectors such
as 'iif' and 'oif'.

In a similar fashion to the previous patch, allow bridges and VLAN
devices on top of bridges to be enslaved to a VRF master device.

Allow port netdevs, LAG and VLAN devices stacked on top of these to be
enslaved to a VRF master device.
Upon enslavement, create a router interface (RIF) for the enslaved
netdev and associate it with a virtual router (VR) based on the VRF's
table ID.
If a RIF already exists for the netdev (f.e., due to the existence of an
IP address), then it's deleted and a new one is created with the
appropriate VR binding.

We usually destroy the netdev's router interface (RIF) when the last IP
address is removed from it.
However, we shouldn't do that if it's enslaved to an L3 master device.

When a router interface (RIF) is created due to a netdev being enslaved
to a VRF master, then it should be associated with the appropriate
virtual router (VR) and not the default one.
If netdev is a VRF slave, lookup the VR based on the VRF's table ID.
Otherwise default to the MAIN table.
