The addition of FLOW_DISSECTOR_KEY_ENC_IP to TC flower means that the ToS
and TTL of the tunnel header can now be matched on.
Extend the NFP tunnel match function to include these new fields.

net: Support Wake-on-LAN using filters
This is technically a v2, but this patch series builds on your feedback
and defines the following:
- a new WAKE_* bit: WAKE_FILTER which can be enabled alongside other type
of Wake-on-LAN to support waking up on a programmed filter (match + action)
- a new RX_CLS_FLOW_WAKE flow action which can be specified by an user when
inserting a flow using ethtool::rxnfc, similar to the existing RX_CLS_FLOW_DISC
The bcm_sf2 and bcmsysport drivers are updated accordingly to work in concert to
allow matching packets at the switch level, identified by their filter location
to be used as a match by the SYSTEM PORT (CPU/management controller) during
Wake-on-LAN.
Let me know if this looks better than the previous incarnation of the patch
series.
Attached is also the ethtool patch that I would be submitting once the uapi
changes are committed.
Thank you!

The SYSTEMPORT MAC allows up to 8 filters to be programmed to wake-up
from LAN. Verify that we have up to 8 filters and program them to the
appropriate RXCHK entries to be matched (along with their masks).
We need to update the entry and exit to Wake-on-LAN mode to keep the
RXCHK engine running to match during suspend, but this is otherwise
fairly similar to Magic Packet detection.

Allow propagating ethtool::rxnfc programming to the CPU/management port
such that it is possible for such a CPU to perform e.g: Wake-on-LAN
using filters configured by the switch. We need a tiny bit of
cooperation between the switch drivers which is able to do the full flow
matching, whereas the CPU/management port might not. The CPU/management
driver needs to return -EOPNOTSUPP to indicate an non critical error,
any other error code otherwise.

Add the ability to specify through ethtool::rxnfc that a rule location is
special and will be used to participate in Wake-on-LAN, by e.g: having a
specific pattern be matched. When this is the case, fs->ring_cookie must
be set to the special value RX_CLS_FLOW_WAKE.
We also define an additional ethtool::wolinfo flag: WAKE_FILTER which
can be used to configure an Ethernet adapter to allow Wake-on-LAN using
previously programmed filters.

pull-request: bpf-next 2018-08-07
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add cgroup local storage for BPF programs, which provides a fast
accessible memory for storing various per-cgroup data like number
of transmitted packets, etc, from Roman.
2) Support bpf_get_socket_cookie() BPF helper in several more program
types that have a full socket available, from Andrey.
3) Significantly improve the performance of perf events which are
reported from BPF offload. Also convert a couple of BPF AF_XDP
samples overto use libbpf, both from Jakub.
4) seg6local LWT provides the End.DT6 action, which allows to
decapsulate an outer IPv6 header containing a Segment Routing Header.
Adds this action now to the seg6local BPF interface, from Mathieu.
5) Do not mark dst register as unbounded in MOV64 instruction when
both src and dst register are the same, from Arthur.
6) Define u_smp_rmb() and u_smp_wmb() to their respective barrier
instructions on arm64 for the AF_XDP sample code, from Brian.
7) Convert the tcp_client.py and tcp_server.py BPF selftest scripts
over from Python 2 to Python 3, from Jeremy.
8) Enable BTF build flags to the BPF sample code Makefile, from Taeung.
9) Remove an unnecessary rcu_read_lock() in run_lwt_bpf(), from Taehee.
10) Several improvements to the README.rst from the BPF documentation
to make it more consistent with RST format, from Tobin.
11) Replace all occurrences of strerror() by calls to strerror_r()
in libbpf and fix a FORTIFY_SOURCE build error along with it,
from Thomas.
12) Fix a bug in bpftool's get_btf() function to correctly propagate
an error via PTR_ERR(), from Yue.

__cgroup_bpf_attach() and __cgroup_bpf_detach() functions have
a good amount of duplicated code, which is possible to eliminate
by introducing the update_effective_progs() helper function.
The update_effective_progs() calls compute_effective_progs()
and then in case of success it calls activate_effective_progs()
for each descendant cgroup. In case of failure (OOM), it releases
allocated prog arrays and return the error code.

We use to have message like:
struct vhost_msg {
int type;
union {
struct vhost_iotlb_msg iotlb;
__u8 padding[64];
};
};
Unfortunately, there will be a hole of 32bit in 64bit machine because
of the alignment. This leads a different formats between 32bit API and
64bit API. What's more it will break 32bit program running on 64bit
machine.
So fixing this by introducing a new message type with an explicit
32bit reserved field after type like:
struct vhost_msg_v2 {
__u32 type;
__u32 reserved;
union {
struct vhost_iotlb_msg iotlb;
__u8 padding[64];
};
};
We will have a consistent ABI after switching to use this. To enable
this capability, introduce a new ioctl (VHOST_SET_BAKCEND_FEATURE) for
userspace to enable this feature (VHOST_BACKEND_F_IOTLB_V2).

This patch adds a new virtual driver mac802154_hwsim which is based on
the fakelb driver.
The fakelb driver will get deprecated and hopefully removed someday.
The main reason for doing this step is to rename the driver to
mac802154_hwsim to have a similar naming scheme as mac80211_hwsim,
which is more popular in the 802.11 wireless word and the idea is the
same behind this driver.
The new features of this driver are to have knowledge about connected
edges, which can be changed during runtime. This offers a testing
environment for routing protocols e.g. RPL.
The default behaviour is still as fakelb: two radios connected to each
other. New added radios during runtime will not be connected to other
wpan_hwsim instances.
The netlink api is not namespace aware on purpose, only the registered
wpan_phy's can be moved to namespaces. The physical layer according to
wiresless "air" communication can be handled across namespaces.
Furthermore the edges can be weighted with the LQI value according IEEE
802.15.4 which offers additional handling to mark bad or good connection
indicators to other connected virtual phys.

mlxsw: Enable MC-aware mode for mlxsw ports
Petr says:
Due to an issue in Spectrum chips, when unicast traffic shares the same
queue as BUM traffic, and there is a congestion, the BUM traffic is
admitted to the queue anyway, thus pushing out all UC traffic. In order
to give unicast traffic precedence over BUM traffic, configure
multicast-aware mode on all ports.
Under multicast-aware regime, when assigning traffic class to a packet,
the switch doesn't merely take the value prescribed by the QTCT
register. For BUM traffic, it instead assigns that value plus 8. That
limits the number of available TCs, but since mlxsw currently only uses
the lower eight anyway, it is no real loss.
The two TCs (UC and MC one) are then mapped to the same subgroup and
strictly prioritized so that UC traffic is preferred in case of
congestion.
In patch #1, introduce a new register, QTCTM, which enables the
multicast-aware mode.
In patch #2, fix a typo in related code.
In patch #3, set up TCs and QTCTM to enable multicast-aware mode.

In order to give unicast traffic precedence over BUM traffic, configure
multicast-aware mode on all ports.
Under multicast-aware regime, when assigning traffic class to a packet,
the switch doesn't merely take the value prescribed by the QTCT
register. For BUM traffic, it instead assigns that value plus 8.
ETS elements for TCs 8..15 thus need to be configured as well. Extend
mlxsw_sp_port_ets_init() so that it maps each of them to the same
subgroup as their corresponding TC from the range 0..7, such that TCs X
and X+8 map to the same subgroup.
The existing code configures TCs with strict priority. So far this was
immaterial, because each TC had its own subgroup. Now that two TCs share
a subgroup it becomes important. TCs are prioritized in order of 7, 6,
..., 0, 15, 14, ..., 8: the higher TCs used for BUM traffic end up being
deprioritized. Since that's what's needed, keep that configuration as it
is, and configure the new TCs likewise.
Finally in mlxsw_sp_port_create(), invoke configuration of QTCTM to
enable MC-aware mode on each port.

don't bother with pathological cases, they only waste cycles.

Also the users could set dts properties by themselves according
to their requirement.

====================
bnxt_en: Updates for net-next.
This series includes the usual firmware spec update. The driver has
added external phy loopback test and phy setup retry logic that is
needed during hotplug. In the SRIOV space, the driver has added a
new VF resource allocation mode that requires the VF driver to
reserve resources during IFUP. IF state changes are now propagated
to firmware so that firmware can release some resources during IFDOWN.
ethtool method to get firmware core dump and hwmon temperature reading
have been added. DSCP to user priority support has been added to
the driver's DCBNL interface, and the CoS queue logic has been refined
to make sure that the special RDMA Congestion Notification hardware CoS
queue will not be used for networking traffic.

The CNP CoS queue is reserved for internal RDMA Congestion Notification
Packets (CNP) and should not be used for a TC. Modify the CoS queue
discovery code to skip over the CNP CoS queue and to reduce
bp->max_tc accordingly. However, if RDMA is disabled in NVRAM, the
the CNP CoS queue can be used for a TC.

Expand the .ieee_setapp() and ieee_delapp() DCBNL methods to support
DSCP. This allows DSCP values to user priority mappings instead
of using VLAN priorities. Each DSCP mapping is added or deleted one
entry at a time using the firmware API. The firmware call can only be
made from a PF.

Use latest firmware API to notify firmware about IF state changes.
Firmware has the option to clean up resources during IF down and
to require the driver to reserve resources again during IF up.
