This change implements MCTP fragmentation (based on route & device MTU),
and corresponding reassembly.
The MCTP specification only allows for fragmentation on the originating
message endpoint, and reassembly on the destination endpoint -
intermediate nodes do not need to reassemble/refragment. Consequently,
we only fragment in the local transmit path, and reassemble
locally-bound packets. Messages are required to be in-order, so we
simply cancel reassembly on out-of-order or missing packets.
In the fragmentation path, we just break up the message into MTU-sized
fragments; the skb structure is a simple copy for now, which we can later
improve with a shared data implementation.
For reassembly, we keep track of incoming message fragments using the
existing tag infrastructure, allocating a key on the (src,dest,tag)
tuple, and reassembles matching fragments into a skb->frag_list.

Start filling-out the socket syscalls: bind, sendmsg & recvmsg.
This requires an input route implementation, so we add to
mctp_route_input, allowing lookups on binds & message tags. This just
handles single-packet messages at present, we will add fragmentation in
a future change.

sk_buff: optimize GRO for the common case
This is a trimmed down revision of "sk_buff: optimize layout for GRO",
specifically dropping the changes to the sk_buff layout[1].
This series tries to accomplish 2 goals:
- optimize the GRO stage for the most common scenario, avoiding a bunch
of conditional and some more code
- let owned skbs entering the GRO engine, allowing backpressure in the
veth GRO forward path.
A new sk_buff flag (!!!) is introduced and maintained for GRO's sake.
Such field uses an existing hole, so there is no change to the sk_buff
size.
[1] two main reasons:
- move skb->inner_ field requires some extra care, as some in kernel
users access and the fields regardless of skb->encapsulation.
- extending secmark size clash with ct and nft uAPIs
address the all above is possible, I think, but for sure not in a single
series.

This change leverages the infrastructure introduced by the previous
patches to allow soft devices passing to the GRO engine owned skbs
without impacting the fast-path.
It's up to the GRO caller ensuring the slow_gro bit validity before
invoking the GRO engine. The new helper skb_prepare_for_gro() is
introduced for that goal.
On slow_gro, skbs are aggregated only with equal sk.
Additionally, skb truesize on GRO recycle and free is correctly
updated so that sk wmem is not changed by the GRO processing.

price of an additional one when we hit the above "slow-paths".

Currently there are issues when adding a bridge FDB entry as VLAN-aware
and deleting it as VLAN-unaware, or vice versa.
However this is an unneeded complication, since the bridge always
installs its default FDB entries in VLAN 0 to match on VLAN-unaware
ports, and in the default_pvid (VLAN 1) to match on VLAN-aware ports.
So instead of trying to outsmart the bridge, just install all entries it
gives us, and they will start matching packets when the vlan_filtering
mode changes.

====================
Plug the last 2 holes in the switchdev notifiers for local FDB entries
The work for trapping local FDB entries to the CPU in switchdev/DSA
started with the "RX filtering in DSA" series:
https://patchwork.kernel.org/project/netdevbpf/cover/20210629140658.2510288-1-olteanv@gmail.com/
and was continued with further improvements such as "Fan out FDB entries
pointing towards the bridge to all switchdev member ports":
https://patchwork.kernel.org/project/netdevbpf/cover/20210719135140.278938-1-vladimir.oltean@nxp.com/
https://patchwork.kernel.org/project/netdevbpf/cover/20210720173557.999534-1-vladimir.oltean@nxp.com/
There are only 2 more issues left to be addressed (famous last words),
and these are:
- dynamically learned FDB entries towards interfaces foreign to DSA need
to be replayed too
- adding/deleting a VLAN on a port causes the local FDB entries in that
VLAN to be prematurely deleted
This patch series addresses both, and patch 2 depends on 1 to work properly.

Currently the following script:
1. ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up
2. ip link set swp2 up && ip link set swp2 master br0
3. ip link set swp3 up && ip link set swp3 master br0
4. ip link set swp4 up && ip link set swp4 master br0
5. bridge vlan del dev swp2 vid 1
6. bridge vlan del dev swp3 vid 1
7. ip link set swp4 nomaster
8. ip link set swp3 nomaster
produces the following output:
[ 641.010738] sja1105 spi0.1: port 2 failed to delete 00:1f:7b:63:02:48 vid 1 from fdb: -2
[ swp2, swp3 and br0 all have the same MAC address, the one listed above ]
In short, this happens because the number of FDB entry additions
notified to switchdev is unbalanced with the number of deletions.
At step 1, the bridge has a random MAC address. At step 2, the
br_fdb_replay of swp2 receives this initial MAC address. Then the bridge
inherits the MAC address of swp2 via br_fdb_change_mac_address(), and it
notifies switchdev (only swp2 at this point) of the deletion of the
random MAC address and the addition of 00:1f:7b:63:02:48 as a local FDB
entry with fdb->dst == swp2, in VLANs 0 and the default_pvid (1).
During step 7:
del_nbp
-> br_fdb_delete_by_port(br, p, vid=0, do_all=1);
-> fdb_delete_local(br, p, f);
br_fdb_delete_by_port() deletes all entries towards the ports,
regardless of vid, because do_all is 1.
fdb_delete_local() has logic to migrate local FDB entries deleted from
one port to another port which shares the same MAC address and is in the
same VLAN, or to the bridge device itself. This migration happens
without notifying switchdev of the deletion on the old port and the
addition on the new one, just fdb->dst is changed and the added_by_user
flag is cleared.
In the example above, the del_nbp(swp4) causes the
"addr 00:1f:7b:63:02:48 vid 1" local FDB entry with fdb->dst == swp4
that existed up until then to be migrated directly towards the bridge
(fdb->dst == NULL). This is because it cannot be migrated to any of the
other ports (swp2 and swp3 are not in VLAN 1).
After the migration to br0 takes place, swp4 requests a deletion replay
of all FDB entries. Since the "addr 00:1f:7b:63:02:48 vid 1" entry now
point towards the bridge, a deletion of it is replayed. There was just
a prior addition of this address, so the switchdev driver deletes this
entry.
Then, the del_nbp(swp3) at step 8 triggers another br_fdb_replay, and
switchdev is notified again to delete "addr 00:1f:7b:63:02:48 vid 1".
But it can't because it no longer has it, so it returns -ENOENT.
There are other possibilities to trigger this issue, but this is by far
the simplest to explain.
To fix this, we must avoid the situation where the addition of an FDB
entry is notified to switchdev as a local entry on a port, and the
deletion is notified on the bridge itself.
Considering that the 2 types of FDB entries are completely equivalent
and we cannot have the same MAC address as a local entry on 2 bridge
ports, or on a bridge port and pointing towards the bridge at the same
time, it makes sense to hide away from switchdev completely the fact
that a local FDB entry is associated with a given bridge port at all.
Just say that it points towards the bridge, it should make no difference
whatsoever to the switchdev driver and should even lead to a simpler
overall implementation, will less cases to handle.
This also avoids any modification at all to the core bridge driver, just
what is reported to switchdev changes. With the local/permanent entries
on bridge ports being already reported to user space, it is hard to
believe that the bridge behavior can change in any backwards-incompatible
way such as making all local FDB entries point towards the bridge.

Currently when a switchdev port joins a bridge, we replay all FDB
entries pointing towards that port or towards the bridge.
However, this is insufficient in certain situations:
(a) DSA, through its assisted_learning_on_cpu_port logic, snoops
dynamically learned FDB entries on foreign interfaces.
These are FDB entries that are pointing neither towards the newly
joined switchdev port, nor towards the bridge. So these addresses
would be missed when joining a bridge where a foreign interface has
already learned some addresses, and they would also linger on if the
DSA port leaves the bridge before the foreign interface forgets them.
None of this happens if we replay the entire FDB when the port joins.
(b) There is a desire to treat local FDB entries on a port (i.e. the
port's termination MAC address) identically to FDB entries pointing
towards the bridge itself. More details on the reason behind this in
the next patch. The point is that this cannot be done given the
current structure of br_fdb_replay() in this situation:
ip link set swp0 master br0 # br0 inherits its MAC address from swp0
ip link set swp1 master br0
What is desirable is that when swp1 joins the bridge, br_fdb_replay()
also notifies swp1 of br0's MAC address, but this won't in fact
happen because the MAC address of br0 does not have fdb->dst == NULL
(it doesn't point towards the bridge), but it has fdb->dst == swp0.
So our current logic makes it impossible for that address to be
replayed. But if we dump the entire FDB instead of just the entries
with fdb->dst == swp1 and fdb->dst == NULL, then the inherited MAC
address of br0 will be replayed too, which is what we need.
A natural question arises: say there is an FDB entry to be replayed,
like a MAC address dynamically learned on a foreign interface that
belongs to a bridge where no switchdev port has joined yet. If 10
switchdev ports belonging to the same driver join this bridge, one by
one, won't every port get notified 10 times of the foreign FDB entry,
amounting to a total of 100 notifications for this FDB entry in the
switchdev driver?
Well, yes, but this is where the "void *ctx" argument for br_fdb_replay
is useful: every port of the switchdev driver is notified whenever any
other port requests an FDB replay, but because the replay was initiated
by a different port, its context is different from the initiating port's
context, so it ignores those replays.
So the foreign FDB entry will be installed only 10 times, once per port.
This is done so that the following 4 code paths are always well balanced:
(a) addition of foreign FDB entry is replayed when port joins bridge
(b) deletion of foreign FDB entry is replayed when port leaves bridge
(c) addition of foreign FDB entry is notified to all ports currently in bridge
(c) deletion of foreign FDB entry is notified to all ports currently in bridge

1PPS (One Pulse Per Second) is a signal generated either
by the NIC PHC or an external timing source.
Integrating the support to configure and use 1PPS using
the TSIO pins along with PTP timestamps will add Grand
Master capability to the 5750X family chipsets.
This patch initializes the driver data structures and
registers the 1PPS with kernel, based on the TSIO pins'
capability in the hardware. This will create a /dev/ppsX
device which applications can use to receive PPS events.
Later patches will define functions to configure and use
the pins.

During error recovery or hot firmware upgrade, the chip may be under
reset and the PHC register read cycles may cause completion timeouts.
Check that the chip is not under reset condition before proceeding
to read the PHC by checking the flag BNXT_STATE_IN_FW_RESET. We also
need to take the ptp_lock before we set this flag to prevent race
conditions.
We need this logic because the PHC now will stay registered after
bnxt_close().

It was pointed out by Richard Cochran that registering the PHC during
probe is better than during ifup, so move bnxt_ptp_init() back to
bnxt_init_one(). In order to work correctly after firmware reset which
may result in PTP config. changes, we modify bnxt_ptp_init() to return
if the PHC has been registered earlier. If PTP is no longer supported
by the new firmware, we will unregister the PHC and clean up.
