Track our used and unused queue indexies correctly. Otherwise, as ports
dropped out and returned, they all eventually ended up with the same
queue index.

In this driver, there is a "port" created for the connection to each of
the other ldoms; a netdev queue is mapped to each port, and they are
collected under a single netdev. The generic netdev statistics show
us all the traffic in and out of our network device, but don't show
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
those connections.

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.

CONFIG_8xx is deprecated and should soon be removed in favor
of CONFIG_PPC_8xx.
Anyway, hfc_multi_8xx.h only uses 8xx I/O ports which are
linked to the CPM1 communication processor included in the 8xx
rather than the 8xx itself.
This patch therefore makes it dependent on CONFIG_CPM1 instead,
like several other drivers.

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'.

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.

Allow listeners of the subsequent CHANGEUPPER notification to retrieve
the VRF's table ID by calling l3mdev_fib_table() with the slave netdev.
Without this change, the netdev won't be considered an L3 slave and the
function would return 0.
This is consistent with other master device such as bridge and bond that
set the slave's private flag before linking. It also makes
do_vrf_{add,del}_slave() symmetric.

In commit c3852ef7f2f8 ("ipv4: fib: Replay events when registering FIB
notifier") we dumped the FIB tables and replayed the events to the
passed notification block.
However, we merely sent a RULE_ADD notification in case custom rules
were in use. As explained in previous patches, this approach won't work
anymore. Instead, we should notify the caller about all the FIB rules
and let it act accordingly.
Upon registration to the FIB notification chain, replay a RULE_ADD
notification for each programmed FIB rule, custom or not. The integrity
of the dump is ensured by the mechanism introduced in the above
mentioned commit.
Prevent regressions by making sure current listeners correctly sanitize
the notified rules.

The configurable priority to traffic class mapping and the user specified
queue ranges are used to configure the traffic class, overriding the
hardware defaults when the 'hw' option is set to 0. However, when the 'hw'
option is non-zero, the hardware QOS defaults are used.
This patch makes it so that we can pass the data the user provided to
ndo_setup_tc. This allows us to pull in the queue configuration if the
user requested it as well as any additional hardware offload type
requested by using a value other than 1 for the hw value.
Finally it also provides a means for the device driver to return the level
supported for the offload type via the qopt->hw value. Previously we were
just always assuming the value to be 1, in the future values beyond just 1
may be supported.

Jeff Kirsher says:
====================
40GbE Intel Wired LAN Driver Updates 2017-03-15
This series contains updates to i40e and i40evf only.
Aaron fixes an issue on x710 devices where simultaneous read accesses
were interfering with each other, so make sure all devices acquire the
NVM lock before reads on all devices.
Shannon adds Wake On LAN support feature for x722 devices and cleaned
up the opcodes so that they are in numerical order.
Mitch adds a client interface to the VF driver, in preparation for the
upcoming RDMA-capable hardware (and client driver). Cleaned up the
client interface in the PF driver, since it was originally over
engineered to handle multiple clients on multiple netdevs, but that
did not happen and now there will be one client per driver, so apply
the "KISS" (Keep It Simple & Stupid) to the i40e client interface.
Bumped the number of MAC filters an untrusted VF can create.
Jake fixes an issue where a recent refactor of queue pairs accidentally
added all remaining vecotrs to the num_lan_msix which can adversely
affect performance.
Lihong fixes an ethtool issue with x722 devices where "-e" will error
out since its EEPROM has a scope limit at offset 0x5B9FFF, so set the
EEPROM length to the scope limit. Also fixed an issue where RSS
offloading only worked on PF0.
Filip cleans up and clarifies code comment so there is no confusion
about MAC/VLAN filter initialization routine.
Alex adds support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING,
which improves performance on architectures that implement either one.
Harshitha cleans up confusion on flags disabled due to hardware limitation
versus featured disabled by the user, so rename auto_disable_flags to
hw_disabled_flags to avoid the confusion.
v2: Merged patch #1 and #4 in first version to make patch #3 in this
series based on feedback from David Miller.

Our original filter limit of 8 was based on behavior that we saw from
Linux VMs. Now we're running Other Operating Systems under KVM and we
see that they commonly use more MAC filters. Since it seems weird to
require people to enable trusted VFs just to boot their OS, bump the
number of filters allowed by default.

This patch adds support for DMA_ATTR_SKIP_CPU_SYNC and
DMA_ATTR_WEAK_ORDERING. By enabling both of these for the Rx path we
are able to see performance improvements on architectures that implement
either one due to the fact that page mapping and unmapping only has to
sync what is actually being used instead of the entire buffer. In addition
by enabling the weak ordering attribute enables a performance improvement
for architectures that can associate a memory ordering with a DMA buffer
such as Sparc.

This is a solution to avoid adding too many queues to num_lan_msix.
A recent refactor of queue pairs accidentally added all remaining
vectors to the num_lan_msix which can have adverse performance issues,
due to enabling more queues than the number of CPU cores.
This patch removes the old calculation, and replaces it with a simple
algorithm.
1) add queue pairs up to num_online_cpus(), but capped at half of total
vectors
2) then add alternative features such as flow directory and similar
3) finally, add the remaining vectors back to queue pairs, but capped
such that the total number of queue pairs does not exceed
num_online_cpus().
