Create representors after lower vNIC is registered and destroy
them before it is destroyed. Move the code out of start/stop
callbacks directly into vnic_init/clean callbacks. Make sure
SR-IOV callbacks don't try to create representors when lower
device does not exist.

We currently only have one app callback for vNIC creation
and destruction. This is insufficient, because some actions
have to be taken before netdev is registered, after it's
registered and after it's unregistered. Old callbacks
were really corresponding to alloc/free actions. Rename
them and add proper init/clean. Apps using representors
will be able to use new callbacks to manage lifetime of
upper devices.

====================
mlxsw: Offloading GRE tunnels
Petr says:
This patch series introduces to mlxsw driver support for offloading
IP-in-IP tunnels in general, and for (subset of) GRE in particular.
This patchset supports two ways of configuring GRE:
- So called "hierarchical configuration", where the GRE device has a bound
dummy device, which is in a different VRF. The VRF with host traffic is
called "overlay", the one with encapsulated traffic is called "underlay".
- So called "flat configuration", where the GRE device doesn't have a bound
device, and overlay and underlay are both in the same VRF (possibly the
default one).
Two routes are then interesting: a route that directs traffic to a GRE
device (which would typically be in overlay VRF, but could be in another
one), and a local route for the tunnel's local address (in underlay).
Handling of these two route types is then introduced as patches to support,
respectively, IPv4 and IPv6 encapsulation and IPv4 decapsulation.
The encap and decap routes then reference a loopback device, a new type of
RIF introduced by this patchset for the specific use of offloading tunnels.
The encap and decap code is abstract with respect to the particulars of
individual L3 tunnel types. This patchset introduces support for GRE
tunnels in particular.
Limitations:
- Each tunnel needs to have a different local address (within a given VRF).
When two tunnels are used that are in conflict, FIB abort is triggered
and the driver ceases offloading FIBs. Full handling of such
configurations needs special setup in the hardware, such that the tunnels
that share an address are dispatched correctly according to their key (or
lack thereof). That's currently not implemented, and to keep things
deterministic, the driver triggers FIB abort.
- A next hop that uses an incompletely-specified tunnel (e.g. such that are
used for LWT) is not offloaded, but doesn't trigger FIB abort like the
above. If such routes end up being in a de facto conflict with other
tunnels, then if there already is an offload for that address, the
traffic for the conflicting tunnel will end up mismatching the
configuration of the offloaded tunnel, and thus gets to slow path through
an error trap.
- GRE checksumming and sequence numbers are not supported and TTL and TOS
need to be set to inherit. Tunnels with a different configuration are not
offloaded and their traffic is trapping to slow path.
Note in particular that TOS of inherit is not the default configuration
and needs to be explicitly specified when the tunnel is created.
- The only feature that is not graciously handled is that if a change is
made to the tunnel, e.g. through "ip tunnel change", such changes are not
reflected in the driver. There is currently no notification mechanism for
these changes. Introduction of this mechanism and its leverage in the
driver will be subject of follow-up work. For now this limitation can be
worked around by removing and re-adding the encap route.

struct mlxsw_sp_rif is a router-private structure, and therefore
everything related to it is as well: parameters, and derived RIF types
including loopbacks. IPIP module needs access to some details of
loopback interfaces, but exporting all the RIF shebang would create too
large an interface.
So instead export just the bare minimum necessary: accessors for RIF
index and underlay VRF ID.

The local route that points at IPIP's underlay device (decap route) can
be present long before the GRE device. Thus when an encap route is
added, it's necessary to look inside the underlay FIB if the decap route
is already present. If so, the current trap offload needs to be
withdrawn and replaced with a decap offload.

Unlike encapsulation, which is represented by a next hop forwarding to
an IPIP tunnel, decapsulation is a type of local route. It is created
for local routes whose prefix corresponds to the local address of one of
offloaded IPIP tunnels. When the tunnel is removed (i.e. all the encap
next hops are removed), the decap offload is migrated back to a trap for
resolution in slow path.
This patch assumes that decap route is already present when encap route
is added. A follow-up patch will fix this issue.
Note that this patch only supports IPv4 underlay. Support for IPv6
underlay will be subject to follow-up work apart from this patchset.

This introduces some common code for tracking of offloaded IP-in-IP
tunnels, and support for offloading IPv4 overlay encapsulating routes in
particular. A follow-up patch will introduce IPv6 overlay as well.
Offloaded tunnels are kept in a linked list of mlxsw_sp_ipip_entry
objects hooked up in mlxsw_sp_router. A network device that represents
the tunnel is used as a key to look up the corresponding IPIP entry.
Note that in the future, more general keying mechanism will be needed,
because parts of the tunnel information can be provided by the route.
IPIP entries are reference counted, because several next hops may end up
using the same tunnel, and we only want to offload it once.
Encapsulation path hooks into next hop handling. Routes that forward to
a tunnel are now considered gateway routes, thus giving them the same
treatment that other remote routes get. An IPIP next hop type is
introduced.
Details of individual tunnel types are kept in an array of
mlxsw_sp_ipip_ops objects. If a tunnel type doesn't match any of the
known tunnel types, the next-hop is not considered an IPIP next hop.
The list of IPIP tunnel types is currently empty, follow-up patches will
add support for GRE. Traffic to IPIP tunnel types that are not
explicitly recognized by the driver traps and is handled in slow path.

In the router, some next hops may reference an encapsulating netdevice,
such as GRE or IPIP. To properly offload these next hops, mlxsw needs to
keep track of whether a given next hop is a regular Ethernet entry, or
an IP-in-IP tunneling entry.
To facilitate this book-keeping, add a type field to struct
mlxsw_sp_nexthop. There is, as of this patch, only one next hop type:
MLXSW_SP_NEXTHOP_TYPE_ETH. Follow-up patches will introduce the IP-in-IP
variant.
There are several places where next hops are initialized in the IPv4
path. Instead of replicating the logic at every one of them, factor it
out to a function mlxsw_sp_nexthop4_type_init(). The corresponding fini
is actually protocol-neutral, so put it to mlxsw_sp_nexthop_type_fini(),
but create a corresponding protocoled _fini function that dispatches to
the protocol-neutral one.
The IPv6 path is simpler, but for symmetry with IPv4, create the same
suite of functions with corresponding logic.

When using a mac address described in the device tree, a check is made
to see if it is valid. When it's not, no fallback is defined. This
patches tries to get the mac address from h/w (or use a random one if
the h/w one isn't valid) when the dt mac address isn't valid.

The MAC retrieval logic is using a variable to store an h/w stored mac
address and checks this mac against invalid ones before using it. But
the mac address is only read from h/w when using PPv2.1. So when using
PPv2.2 it defaults to its init state.
This patches fixes the logic to only check if the h/w mac is valid when
actually retrieving a mac from h/w.

Pull rdma updates from Doug Ledford:
"This is a big pull request.
Of note is that I'm sending you the new ioctl API for the rdma
subsystem. We put it up on linux-api@, but didn't get much response.
The API is complex, but it solves two different problems in one go:
1) The bi-directional nature of the RDMA file write calls, which
created the security hole we had to handle (and for which the fix
is now causing problems for systems in production, we were a bit
over zealous in the fix and the ability to open a device, then
fork, then create new queue pairs on the device and use them is
broken).
2) The bloat caused by different vendors implementing extensions to
the base verbs API. Each vendor's hardware is slightly different,
and the hardware might be suitable for one extension but not
another.
By the time we add generic extensions for all the different ways
that the different hardware can offload things, the API becomes
bloated. Things like our completion structs have started to exceed
a cache line in size because of all the elements needed to support
this. That in turn shows up heavily in the performance graphs with
a noticable drop in performance on 100Gigabit links as our
completion structs go from occupying one cache line to 1+.
This API makes things like the completion structs modular in a
very similar way to netlink so that your structs can only include
the items needed for the offloads/features you are actually using
on a given queue pair. In that way we support everything, but only
use what we need, and our structs stay smaller.
The ioctl API is better explained by the posting on linux-api@ than I
can explain it here, so I'll just leave it at that.
The rest of the pull request is typical stuff.

13) Remove neededlessly branch in nf_tables trace code, from Phil Sutter.
14) Add nla_strdup(), from Phil Sutter.
15) Rise nf_tables objects name size up to 255 chars, people want to use
DNS names, so increase this according to what RFC 1035 specifies.

16) Kill nf_conntrack_default_on, it's broken. Default on conntrack hook
registration on demand, suggested by Eric Dumazet, patch from Florian.
17) Remove unused variables in compat_copy_entry_from_user both in
ip_tables and arp_tables code. Patch from Taehee Yoo.
18) Constify struct nf_conntrack_l4proto, from Julia Lawall.
19) Constify nf_loginfo structure, also from Julia.
20) Use a single rb root in connlimit, from Taehee Yoo.
21) Remove unused netfilter_queue_init() prototype, from Taehee Yoo.
22) Use audit_log() instead of open-coding it, from Geliang Tang.
23) Allow to mangle tcp options via nft_exthdr, from Florian.
24) Allow to fetch TCP MSS from nft_rt, from Florian. This includes
a fix for a miscalculation of the minimal length.
25) Simplify branch logic in h323 helper, from Nick Desaulniers.
26) Calculate netlink attribute size for conntrack tuple at compile
time, from Florian.
27) Remove protocol name field from nf_conntrack_{l3,l4}proto structure.
From Florian.
28) Remove holes in nf_conntrack_l4proto structure, so it becomes

29) Get rid of print_tuple() indirection for /proc conntrack listing.
Place all the code in net/netfilter/nf_conntrack_standalone.c.
Patch from Florian.
30) Do not built in print_conntrack() if CONFIG_NF_CONNTRACK_PROCFS is
off. From Florian.
31) Constify most nf_conntrack_{l3,l4}proto helper functions, from
Florian.
32) Fix broken indentation in ebtables extensions, from Colin Ian King.
33) Fix several harmless sparse warning, from Florian.
34) Convert netfilter hook infrastructure to use array for better memory
locality, joint work done by Florian and Aaron Conole. Moreover, add
some instrumentation to debug this.
35) Batch nf_unregister_net_hooks() calls, to call synchronize_net once
per batch, from Florian.
36) Get rid of noisy logging in ICMPv6 conntrack helper, from Florian.
37) Get rid of obsolete NFDEBUG() instrumentation, from Varsha Rao.
38) Remove unused code in the generic protocol tracker, from Davide
Caratti.
I think I will have material for a second Netfilter batch in my queue if
time allow to make it fit in this merge window.

Pull drm updates from Dave Airlie:
"This is the main drm pull request for 4.14 merge window.
I'm sending this early, as my continuing journey into fatherhood is
occurring really soon now, I'm going to be mostly useless for the next

doing much patch applications or git sending. If anything urgent pops
up I've asked Daniel/Jani/Alex/Sean to try and direct stuff towards
you.

Pull misc fixes from Al Viro:
"Loose ends and regressions from the last merge window.
Strictly speaking, only binfmt_flat thing is a build regression per
se - the rest is 'only sparse cares about that' stuff"

was late in the release and nothing seemed critical enough to care, so
