1GbE Intel Wired LAN Driver Updates 2018-04-25

This series enables some ethtool and tc-flower filters to be offloaded
to igb-based network controllers. This is useful when the system
configuration wants to steer kinds of traffic to a specific hardware
queue for i210 devices only.

The first two patch in the series are bug fixes.

The basis of this series is to export the internal API used to
configure address filters, so they can be used by ethtool, and
extending the functionality so an source address can be handled.

Then, we enable the tc-flower offloading implementation to re-use the
same infrastructure as ethtool, and storing them in the per-adapter
"nfc" (Network Filter Config?) list. But for consistency, for
destructive access they are separated, i.e. an filter added by
tc-flower can only be removed by tc-flower, but ethtool can read them
all.

Only support for VLAN Prio, Source and Destination MAC Address, and
Ethertype is enabled for now.

10GbE Intel Wired LAN Driver Updates 2018-04-25

This series represents yet another phase of the macvlan cleanup Alex has
been working on.

The main goal of these changes is to make it so that we only support
offloading what we can actually offload and we don't break any existing
functionality. So for example we were claiming to advertise source mode
macvlan and we were doing nothing of the sort, so support for that has been
dropped.

The biggest change with this set is that broadcast/multicast replication is
no longer being supported in software. Alex dropped it as it leads to
scaling issues when a broadcast frame has to be replicated up to 64 times.

Beyond that this set goes through and optimized the time needed to bring up
and tear down the macvlan interfaces on ixgbe and provides a clean way for
us to disable the macvlan offload when needed.

This allows filters added by tc-flower and specifying MAC addresses,
Ethernet types, and the VLAN priority field, to be offloaded to the
controller.

This reuses most of the infrastructure used by ethtool, but clsflower
filters are kept in a separated list, so they are invisible to
ethtool.

To setup clsflower offloading:

$ tc qdisc replace dev eth0 handle 100: parent root mqprio \
     	   	   num_tc 3 map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \
		   queues 1@0 1@1 2@2 hw 0
(clsflower offloading depends on the netword driver to be configured
with multiple traffic classes, we use mqprio's 'num_tc' parameter to
set it to 3)

$ tc qdisc add dev eth0 ingress

Examples of filters:

$ tc filter add dev eth0 parent ffff: flower \
     	    dst_mac aa:aa:aa:aa:aa:aa \
	    hw_tc 2 skip_sw
(just a simple filter filtering for the destination MAC address and
steering that traffic to queue 2)

$ tc filter add dev enp2s0 parent ffff: proto 0x22f0 flower \
     	    src_mac cc:cc:cc:cc:cc:cc \
	    hw_tc 1 skip_sw
(as the i210 doesn't support steering traffic based on the source
address alone, we need to use another steering traffic, in this case
we are using the ethernet type (0x22f0) to steer traffic to queue 1)

nfp: flower tc block support and nfp PCI updates

This series improves the nfp PCIe code by making use of the new
pcie_print_link_status() helper and resetting NFP locks when
driver loads.  This can help us avoid lock ups after host crashes
and is rebooted with PCIe reset or when kdump kernel is loaded.

The flower changes come from John, he says:

This patchset fixes offload issues when multiple repr netdevs are bound to
a tc block and filter rules added. Previously the rule would be passed to
the reprs and would be rejected in all but the first as the cookie value
will indicate a duplicate. The first patch extends the flow lookup
function to consider both host context and ingress netdev along with the
cookie value. This means that a rule with a given cookie can exist
multiple times assuming the ingress netdev is different. The host context
ensures that stats from fw are associated with the correct instance of the
rule.

The second patch protects against rejecting add/del/stat messages when a
rule has a repr as both an ingress port and an egress dev. In such cases a
callback can be triggered twice (once for ingress and once for egress)
and can lead to duplicate rule detection or incorrect double calls.

This adds the capability of configuring the queue steering of arriving
packets based on their source and destination MAC addresses.

Source address steering (i.e. driving traffic to a specific queue),
for the i210, does not work, but filtering does (i.e. accepting
traffic based on the source address). So, trying to add a filter
specifying only a source address will be an error.

In practical terms this adds support for the following use cases,
characterized by these examples:

$ ethtool -N eth0 flow-type ether dst aa:aa:aa:aa:aa:aa action 0
(this will direct packets with destination address "aa:aa:aa:aa:aa:aa"

ECMP (equal-cost multipath) hashes are typically computed on the packets'
5-tuple(src IP, dst IP, src port, dst port, L4 proto).

For encapsulated packets, the L4 data is not readily available and ECMP
hashing will often revert to (src IP, dst IP). This will lead to traffic
polarization on a single ECMP path, causing congestion and waste of network
capacity.

In IPv6, the 20-bit flow label field is also used as part of the ECMP hash.
In the lack of L4 data, the hashing will be on (src IP, dst IP, flow
label). Having a non-zero flow label is thus important for proper traffic
load balancing when L4 data is unavailable (i.e., when packets are
encapsulated).

Currently, the seg6_do_srh_encap() function extracts the original packet's
flow label and set it as the outer IPv6 flow label. There are two issues
with this behaviour:

a) There is no guarantee that the inner flow label is set by the source.
b) If the original packet is not IPv6, the flow label will be set to
zero (e.g., IPv4 or L2 encap).

This patch adds a function, named seg6_make_flowlabel(), that computes a
flow label from a given skb. It supports IPv6, IPv4 and L2 payloads, and
leverages the per namespace 'seg6_flowlabel" sysctl value.

The currently support behaviours are as follows:
-1 set flowlabel to zero.
0 copy flowlabel from Inner paceket in case of Inner IPv6
(Set flowlabel to 0 in case IPv4/L2)
1 Compute the flowlabel using seg6_make_flowlabel()

This patch has been tested for IPv6, IPv4, and L2 traffic.

The original implementation for macvlan offload has us performing a full
port reset every time we added a new macvlan. This shouldn't be necessary
and can be avoided with a few behavior changes.

This patches updates the logic for the queues so that we have essentially 3
possible configurations for macvlan offload. They consist of 15 macvlans
with 4 queues per macvlan, 31 macvlans with 2 queues per macvlan, and 63
macvlans with 1 queue per macvlan. As macvlans are added you will encounter
up to 3 total resets if you add all the way up to 63, and after that the
device will stay in the mode supporting up to 63 macvlans until the L2FW

This change makes it so that we use a software path for packets that are
going to be locally switched between two macvlan interfaces on the same
device. In addition we resort to software replication of broadcast and
multicast packets instead of offloading that to hardware.

The general idea is that using the device for east/west traffic local to
the system is extremely inefficient. We can only support up to whatever the
PCIe limit is for any given device so this caps us at somewhere around 20G
for devices supported by ixgbe. This is compounded even further when you
take broadcast and multicast into account as a single 10G port can come to
a crawl as a packet is replicated up to 60+ times in some cases. In order
to get away from that I am implementing changes so that we handle
broadcast/multicast replication and east/west local traffic all in
software.
