The old ethtool api (get_setting and set_setting) has generic mii
functions mii_ethtool_sset and mii_ethtool_gset.
To support the new ethtool api ({get|set}_link_ksettings), we add
two generics mii function mii_ethtool_{get|set}_link_ksettings_get.

mlx4 XDP TX refactor
This patchset refactors the XDP forwarding case, so that
its dedicated transmit queues are managed in a complete
separation from the other regular ones.
It also adds ethtool counters for XDP cases.

Thanks,

* Exposed per ring counters.

XDP statistics are reported in ethtool, in total and per ring,
as follows:
- xdp_drop: the number of packets dropped by xdp.
- xdp_tx: the number of packets forwarded by xdp.
- xdp_tx_full: the number of times an xdp forward failed
due to a full tx xdp ring.
In addition, all packets that are dropped/forwarded by XDP
are no longer accounted in rx_packets/rx_bytes of the ring,
so that they count traffic that is passed to the stack.

Separately manage the two types of TX rings: regular ones, and XDP.
Upon an XDP set, do not borrow regular TX rings and convert them
into XDP ones, but allocate new ones, unless we hit the max number
of rings.
Which means that in systems with smaller #cores we will not consume
the current TX rings for XDP, while we are still in the num TX limit.
XDP TX rings counters are not shown in ethtool statistics.
Instead, XDP counters will be added to the respective RX rings
in a downstream patch.
This has no performance implications.

Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next
tree. This includes better integration with the routing subsystem for
nf_tables, explicit notrack support and smaller updates. More
specifically, they are:
1) Add fib lookup expression for nf_tables, from Florian Westphal. This
new expression provides a native replacement for iptables addrtype
and rp_filter matches. This is more flexible though, since we can
populate the kernel flowi representation to inquire fib to
accomodate new usecases, such as RTBH through skb mark.
2) Introduce rt expression for nf_tables, from Anders K. Pedersen. This
new expression allow you to access skbuff route metadata, more
specifically nexthop and classid fields.
3) Add notrack support for nf_tables, to skip conntracking, requested by
many users already.
4) Add boilerplate code to allow to use nf_log infrastructure from
nf_tables ingress.
5) Allow to mangle pkttype from nf_tables prerouting chain, to emulate
the xtables cluster match, from Liping Zhang.
6) Move socket lookup code into generic nf_socket_* infrastructure so
we can provide a native replacement for the xtables socket match.
7) Make sure nfnetlink_queue data that is updated on every packets is
placed in a different cache from read-only data, from Florian Westphal.
8) Handle NF_STOLEN from nf_tables core, also from Florian Westphal.
9) Start round robin number generation in nft_numgen from zero,
instead of n-1, for consistency with xtables statistics match,
patch from Liping Zhang.
10) Set GFP_NOWARN flag in skbuff netlink allocations in nfnetlink_log,
given we retry with a smaller allocation on failure, from Calvin Owens.
11) Cleanup xt_multiport to use switch(), from Gao feng.

After call nft_data_init, size is already validated and desc.len will

Introduces an nftables rt expression for routing related data with support
for nexthop (i.e. the directly connected IP address that an outgoing packet
is sent to), which can be used either for matching or accounting, eg.
# nft add rule filter postrouting \
ip daddr 192.168.1.0/24 rt nexthop != 192.168.0.1 drop
This will drop any traffic to 192.168.1.0/24 that is not routed via
192.168.0.1.
# nft add rule filter postrouting \
flow table acct { rt nexthop timeout 600s counter }
# nft add rule ip6 filter postrouting \
flow table acct { rt nexthop timeout 600s counter }
These rules count outgoing traffic per nexthop. Note that the timeout
releases an entry if no traffic is seen for this nexthop within 10 minutes.
# nft add rule inet filter postrouting \
ether type ip \
flow table acct { rt nexthop timeout 600s counter }
# nft add rule inet filter postrouting \
ether type ip6 \
flow table acct { rt nexthop timeout 600s counter }
Same as above, but via the inet family, where the ether type must be
specified explicitly.
"rt classid" is also implemented identical to "meta rtclassid", since it
is more logical to have this match in the routing expression going forward.

Add FIB expression, supported for ipv4, ipv6 and inet family (the latter
just dispatches to ipv4 or ipv6 one based on nfproto).
Currently supports fetching output interface index/name and the
rtm_type associated with an address.
This can be used for adding path filtering. rtm_type is useful
to e.g. enforce a strong-end host model where packets
are only accepted if daddr is configured on the interface the
packet arrived on.
The fib expression is a native nftables alternative to the
xtables addrtype and rp_filter matches.
FIB result order for oif/oifname retrieval is as follows:
- if packet is local (skb has rtable, RTF_LOCAL set, this
will also catch looped-back multicast packets), set oif to
the loopback interface.
- if fib lookup returns an error, or result points to local,
store zero result. This means '--local' option of -m rpfilter
is not supported. It is possible to use 'fib type local' or add
explicit saddr/daddr matching rules to create exceptions if this
is really needed.
- store result in the destination register.
In case of multiple routes, search set for desired oif in case
strict matching is requested.
ipv4 and ipv6 behave fib expressions are supposed to behave the same.

Enable support for IPv4 multicast:
- similar to unicast the flow struct is updated to L3 master device
if relevant prior to calling fib_rules_lookup. The table id is saved
to the lookup arg so the rule action for ipmr can return the table
associated with the device.
- ip_mr_forward needs to check for master device mismatch as well
since the skb->dev is set to it
- allow multicast address on VRF device for Rx by checking for the
daddr in the VRF device as well as the original ingress device
- on Tx need to drop to __mkroute_output when FIB lookup fails for
multicast destination address.
- if CONFIG_IP_MROUTE_MULTIPLE_TABLES is enabled VRF driver creates
IPMR FIB rules on first device create similar to FIB rules. In
addition the VRF driver does not divert IPv4 multicast packets:
it breaks on Tx since the fib lookup fails on the mcast address.

tipc: socket layer improvements
The following issues with the current socket layer hinders socket diagnostics
implementation, which led to this patch series.
1. tipc socket state is derived from multiple variables like
sock->state, tsk->probing_state and tsk->connected. This style forces
us to export multiple attributes to the user space, which has to be
backward compatible.
2. Abuse of sock->state cannot be exported to user-space without
requiring tipc specific hacks in the user-space.
- For connection less (CL) sockets sock->state is overloaded to
tipc state SS_READY.
- For connection oriented (CO) listening socket sock->state is
overloaded to tipc state SS_LISTEN.
This series is split into four:
1. Bug fixes in patch #1,2,3.
2. Minor cleanups in patch#4-5.
3. Express all tipc states using a single variable in patch#6-8.
4. Migrate the new tipc states to sk->sk_state in patch#9-16.
The figures below represents the FSM after this series:
Stream Server Listening Socket:
+-----------+ +-------------+
| TIPC_OPEN |------>| TIPC_LISTEN |
+-----------+ +-------------+
Stream Server Data Socket:
+-----------+ +------------------+
| TIPC_OPEN |------>| TIPC_ESTABLISHED |
+-----------+ +------------------+

| TIPC_DISCONNECTING |

NOTE:
This is just a base refractoring required for socket diagnostics.
TIPC socket diagnostics support will be introduced in a later series.
v2: - remove extra cast and parenthesis as suggested by David S. Miller in #4.
- map new tipc state values to tcp states to address Eric Dumazet's concern,
thus allow the usage of generic sk_* helpers. This is done in patch#10-15.
- remove TIPC_PROBING state and replace it with probe_unacked flag in #11.
- replace the TIPC_CLOSING state in v1 with sk_shutdown flag in #14.
- introduce __tipc_shutdown() to avoid code duplication in #14.
