Cleanup for the bridge replay helpers

This patch series brings some improvements to the logic added to the
bridge and DSA to handle LAG interfaces sandwiched between a bridge and
a DSA switch port.

        br0
        /  \
       /    \
     bond0  swp2
     /  \
    /    \
  swp0  swp1

In particular, it ensures that the switchdev object additions and
deletions are well balanced per physical port. This is important for
future work in the area of offloading local bridge FDB entries to
hardware in the context of DSA requesting a replay of those entries at
bridge join time (this will be submitted in a future patch series).
Due to some difficulty ensuring that the deletion of local FDB entries
pointing towards the bridge device itself is notified to switchdev in
time (before the switchdev port disconnects from the bridge), this is
potentially still not the final form in which the replay helpers will
exist. I'm thinking about moving from the pull mode (in which DSA
requests the replay) to a push mode (in which the bridge initiates the
replay). Nonetheless, these preliminary changes are needed either way.

The patch series also addresses some feedback from Nikolai which is long
overdue by now (sorry).

Switchdev driver maintainers were deliberately omitted due to the
trivial nature of the driver changes (just a function prototype).

Changes in v2:
- fix build issue in patch 4 (function prototype mismatch)
- move switchdev object unsync to the NETDEV_PRECHANGEUPPER code path
====================

When a DSA switch port leaves a bonding interface that is under a
bridge, there might be dangling switchdev objects on that port left
behind, because the bridge is not aware that its lower interface (the
bond) changed state in any way.

Call the bridge replay helpers with adding=false before changing
dp->bridge_dev to NULL, because we need to simulate to
dsa_slave_port_obj_del() that these notifications were emitted by the
bridge.

We add this hook to the NETDEV_PRECHANGEUPPER event handler, because
we are calling into switchdev (and the __switchdev_handle_port_obj_del
fanout helpers expect the upper/lower adjacency lists to still be valid)
and PRECHANGEUPPER is the last moment in time when they still are.

When a switchdev port leaves a LAG that is a bridge port, the switchdev
objects and port attributes offloaded to that port are not removed:

ip link add br0 type bridge
ip link add bond0 type bond mode 802.3ad
ip link set swp0 master bond0
ip link set bond0 master br0
bridge vlan add dev bond0 vid 100
ip link set swp0 nomaster

VLAN 100 will remain installed on swp0 despite it going into standalone
mode, because as far as the bridge is concerned, nothing ever happened
to its bridge port.

Let's extend the bridge vlan, fdb and mdb replay functions to take a
'bool adding' argument, and make DSA and ocelot call the replay
functions with 'adding' as false from the switchdev unsync path, for the
switch port that leaves the bridge.

Note that this patch in itself does not salvage anything, because in the
current pull mode of operation, DSA still needs to call the replay
helpers with adding=false. This will be done in another patch.

There is a slight inconvenience in the switchdev replay helpers added
recently, and this is when:

ip link add br0 type bridge
ip link add bond0 type bond
ip link set bond0 master br0
bridge vlan add dev bond0 vid 100
ip link set swp0 master bond0
ip link set swp1 master bond0

Since the underlying driver (currently only DSA) asks for a replay of
VLANs when swp0 and swp1 join the LAG because it is bridged, what will
happen is that DSA will try to react twice on the VLAN event for swp0.
This is not really a huge problem right now, because most drivers accept
duplicates since the bridge itself does, but it will become a problem
when we add support for replaying switchdev object deletions.

Let's fix this by adding a blank void *ctx in the replay helpers, which
will be passed on by the bridge in the switchdev notifications. If the
context is NULL, everything is the same as before. But if the context is
populated with a valid pointer, the underlying switchdev driver
(currently DSA) can use the pointer to 'see through' the bridge port
(which in the example above is bond0) and 'know' that the event is only
for a particular physical port offloading that bridge port, and not for
all of them.

In the case where the driver asks for a replay of a certain type of
event (port object or attribute) for a bridge port that is a LAG, it may
do so because this port has just joined the LAG.

But there might already be other switchdev ports in that LAG, and it is
preferable that those preexisting switchdev ports do not act upon the
replayed event.

The solution is to add a context to switchdev events, which is NULL most
of the time (when the bridge layer initiates the call) but which can be
set to a value controlled by the switchdev driver when a replay is
requested. The driver can then check the context to figure out if all
ports within the LAG should act upon the switchdev event, or just the
ones that match the context.

We have to modify all switchdev_handle_* helper functions as well as the
prototypes in the drivers that use these helpers too, because these
helpers hide the underlying struct switchdev_notifier_info from us and
there is no way to retrieve the context otherwise.

The context structure will be populated and used in later patches.

FB_MTU is used in 'tipc_msg_build()' to alloc smaller skb when memory
allocation fails, which can avoid unnecessary sending failures.

The value of FB_MTU now is 3744, and the data size will be:

  (3744 + SKB_DATA_ALIGN(sizeof(struct skb_shared_info)) + \
    SKB_DATA_ALIGN(BUF_HEADROOM + BUF_TAILROOM + 3))

which is larger than one page(4096), and two pages will be allocated.

To avoid it, replace '3744' with a calculation:

  (PAGE_SIZE - SKB_DATA_ALIGN(BUF_OVERHEAD) - \
    SKB_DATA_ALIGN(sizeof(struct skb_shared_info)))

What's more, alloc_skb_fclone() will call SKB_DATA_ALIGN for data size,
and it's not necessary to make alignment for buf_size in
tipc_buf_acquire(). So, just remove it.

net: reset MAC header consistently across L3 virtual devices

Some virtual L3 devices, like vxlan-gpe and gre (in collect_md mode),
reset the MAC header pointer after they parsed the outer headers. This
accurately reflects the fact that the decapsulated packet is pure L3
packet, as that makes the MAC header 0 bytes long (the MAC and network
header pointers are equal).

However, many L3 devices only adjust the network header after
decapsulation and leave the MAC header pointer to its original value.
This can confuse other parts of the networking stack, like TC, which
then considers the outer headers as one big MAC header.

This patch series makes the following L3 tunnels behave like VXLAN-GPE:
bareudp, ipip, sit, gre, ip6gre, ip6tnl, gtp.

The case of gre is a bit special. It already resets the MAC header
pointer in collect_md mode, so only the classical mode needs to be
adjusted. However, gre also has a special case that expects the MAC
header pointer to keep pointing to the outer header even after
decapsulation. Therefore, patch 4 keeps an exception for this case.

Ideally, we'd centralise the call to skb_reset_mac_header() in
ip_tunnel_rcv(), to avoid manual calls in ipip (patch 2),
sit (patch 3) and gre (patch 4). That's unfortunately not feasible
currently, because of the gre special case discussed above that
precludes us from resetting the MAC header unconditionally.

The original motivation is to redirect bareudp packets to Ethernet
devices (as described in patch 1). The rest of this series aims at
bringing consistency across all L3 devices (apart from gre's special
case unfortunately).

Note: the gtp patch results from pure code inspection and has been
compiled tested only.

Reset the mac_header pointer even when the tunnel transports only L3

This prevents other parts of the stack from mistakenly accessing the
outer header after the packet has been decapsulated.

In practice, this allows to push an Ethernet header to ipip6, ip6ip6,
mplsip6 or ip6gre packets and redirect them to an Ethernet device:

ipgre_header_parse() seems to be the only case that requires mac_header
to point to the outer header. We can detect this case accurately by
checking ->header_ops. For all other cases, we can reset mac_header.

This allows to push an Ethernet header to ipgre packets and redirect
them to an Ethernet device:

  $ tc filter add dev gre0 ingress matchall          \
