If the smc module is unloaded return control from exit routine only,
if all link groups are freed.
If an IB device is thrown away return control from device removal only,
if all link groups belonging to this device are freed.
Counters for the total number of SMCR link groups and for the total
number of SMCR links per IB device are introduced. smc module unloading
continues only if the total number of SMCR link groups is zero. IB device
removal continues only it the total number of SMCR links per IB device
has decreased to zero.

The nla_put_u16/nla_put_u32 makes sure that
*attrlen is align. The call tree is that:
nla_put_u16/nla_put_u32
-> nla_put attrlen = sizeof(u16) or sizeof(u32)
-> __nla_put attrlen
-> __nla_reserve attrlen
-> skb_put(skb, nla_total_size(attrlen))
nla_total_size returns the total length of attribute
including padding.

While it is entirely possible that this tagger format is in fact more
generic than just these 2 switch families, I don't have that knowledge.
The Seville switch in NXP T1040 has a similar frame format, but there
are enough differences (e.g. DEST field starts at bit 57 instead of 56)
that calling this file tag_vitesse.c is a bit of a stretch at the
moment. The frame format has been listed in a comment so that people who
add support for further Vitesse switches can rework this tagger while
keeping compatibility with Felix.
The "ocelot" name was chosen instead of "felix" because even the Ocelot
switch can act as a DSA device when it is used in NPI mode, and the Felix
tagger format is almost identical. Currently it is only used for the
Felix switch embedded in the NXP LS1028A chip.
The ABI for this tagger should be considered "not stable" at the moment.
The DSA tag is always placed before the Ethernet header and therefore,
we are using the long prefix for RX tags to avoid putting the DSA master
port in promiscuous mode. Once there will be an API in DSA for drivers
to request DSA masters to be in promiscuous mode unconditionally, we
will switch to the "no prefix" extraction frame header, which will save
16 padding bytes for each RX frame.

a link.
Dismiss tx pending slots already when terminating a link group to
exploit termination shortcut in tx completion queue handler.
And kill the completion queue tasklets after destroy of the
completion queues, otherwise there is a time window for another
tasklet schedule of an already killed tasklet.

A final cleanup due to SMCD device removal means immediate freeing
of all link groups belonging to this device in interrupt context.
This patch introduces a separate SMCD link group termination routine,
which terminates all link groups of an SMCD device.
This new routine smcd_terminate_all ()is reused if the smc module is
unloaded.

SMCD link group termination is called when peer signals its shutdown
of its corresponding link group. For regular shutdowns no connections
exist anymore. For abnormal shutdowns connections must be killed and
their DMBs must be unregistered immediately. That means the SMCR method
to delay the link group freeing several seconds does not fit.
This patch adds immediate termination of a link group and its SMCD
connections and makes sure all SMCD link group related cleanup steps
are finished.

If peer announces shutdown, use the link group terminate worker for
local cleanup of link groups and connections to terminate link group
in proper context.
Make sure link groups are cleaned up first before destroying the
event queue of the SMCD device, because link group cleanup may
raise events.
Send signal shutdown only if peer has not done it already.
Send socket abort or close only, if peer has not already announced
shutdown.

When we are looking for a socket bound to a specific address,
we also have to take into account the CID.
This patch is useful with multi-transports support because it
allows the binding of the same port with different CID, and
it prevents a connection to a wrong socket bound to the same
port, but with different CID.

To allow other transports to be loaded with vmci_transport,
we register the vmci_transport as G2H or H2G only when a VMCI guest
or host is active.
To do that, this patch adds a callback registered in the vmci driver
that will be called when the host or guest becomes active.
This callback will register the vmci_transport in the VSOCK core.

This patch adds the support of multiple transports in the
VSOCK core.
With the multi-transports support, we can use vsock with nested VMs
(using also different hypervisors) loading both guest->host and
host->guest transports at the same time.
Major changes:
- vsock core module can be loaded regardless of the transports
- vsock_core_init() and vsock_core_exit() are renamed to
vsock_core_register() and vsock_core_unregister()
- vsock_core_register() has a feature parameter (H2G, G2H, DGRAM)
to identify which directions the transport can handle and if it's
support DGRAM (only vmci)
- each stream socket is assigned to a transport when the remote CID
is set (during the connect() or when we receive a connection request
on a listener socket).
The remote CID is used to decide which transport to use:
- remote CID <= VMADDR_CID_HOST will use guest->host transport;
- remote CID == local_cid (guest->host transport) will use guest->host
transport for loopback (host->guest transports don't support loopback);
- remote CID > VMADDR_CID_HOST will use host->guest transport;
- listener sockets are not bound to any transports since no transport
operations are done on it. In this way we can create a listener
socket, also if the transports are not loaded or with VMADDR_CID_ANY
to listen on all transports.
- DGRAM sockets are handled as before, since only the vmci_transport
provides this feature.

Remote peer is always the host, so we set VMADDR_CID_HOST as
remote CID instead of VMADDR_CID_ANY.

vsock_insert_unbound() was called only when 'sock' parameter of
__vsock_create() was not null. This only happened when
__vsock_create() was called by vsock_create().
In order to simplify the multi-transports support, this patch
moves vsock_insert_unbound() at the end of vsock_create().

All transports call __vsock_create() with the same parameters,
most of them depending on the parent socket. In order to simplify
the VSOCK core APIs exposed to the transports, this patch adds
the vsock_create_connected() callable from transports to create
a new socket when a connection request is received.
We also unexported the __vsock_create().

virtio_transport and vmci_transport handle the buffer_size
sockopts in a very similar way.
In order to support multiple transports, this patch moves this
handling in the core to allow the user to change the options
also if the socket is not yet assigned to any transport.
This patch also adds the '.notify_buffer_size' callback in the
'struct virtio_transport' in order to inform the transport,
when the buffer_size is changed by the user. It is also useful
to limit the 'buffer_size' requested (e.g. virtio transports).

Since now the 'struct vsock_sock' object contains a pointer to
the transport, this patch adds a parameter to the
vsock_core_get_transport() to return the right transport
assigned to the socket.
This patch modifies also the virtio_transport_get_ops(), that
uses the vsock_core_get_transport(), adding the
'struct vsock_sock *' parameter.

We are going to add 'struct vsock_sock *' parameter to
virtio_transport_get_ops().
In some cases, like in the virtio_transport_reset_no_sock(),
we don't have any socket assigned to the packet received,
so we can't use the virtio_transport_get_ops().
In order to allow virtio_transport_reset_no_sock() to use the
'.send_pkt' callback from the 'vhost_transport' or 'virtio_transport',
we add the 'struct virtio_transport *' to it and to its caller:
virtio_transport_recv_pkt().
We moved the 'vhost_transport' and 'virtio_transport' definition,
to pass their address to the virtio_transport_recv_pkt().

As a preparation to support multiple transports, this patch adds
the 'transport' member at the 'struct vsock_sock'.
This new field is initialized during the creation in the
__vsock_create() function.
This patch also renames the global 'transport' pointer to
'transport_single', since for now we're only supporting a single
transport registered at run-time.

When using the kernel datapath, the upcall don't
include skb hash info relatived. That will introduce
some problem, because the hash of skb is important
in kernel stack. For example, VXLAN module uses
it to select UDP src port. The tx queue selection
may also use the hash in stack.
Hash is computed in different ways. Hash is random
for a TCP socket, and hash may be computed in hardware,
or software stack. Recalculation hash is not easy.
Hash of TCP socket is computed:
tcp_v4_connect
-> sk_set_txhash (is random)
__tcp_transmit_skb
-> skb_set_hash_from_sk
There will be one upcall, without information of skb
hash, to ovs-vswitchd, for the first packet of a TCP
session. The rest packets will be processed in Open vSwitch
modules, hash kept. If this tcp session is forward to
VXLAN module, then the UDP src port of first tcp packet
is different from rest packets.
TCP packets may come from the host or dockers, to Open vSwitch.
To fix it, we store the hash info to upcall, and restore hash
when packets sent back.

The xfrm_if(s) on each netns can be deleted when its xfrmi dev is
deleted. xfrmi dev's removal can happen when:
a. netns is being removed and all xfrmi devs will be deleted.
b. rtnl_link_unregister(&xfrmi_link_ops) in xfrmi_fini() when
xfrm_interface.ko is being unloaded.
So there's no need to use xfrmi_exit_net() to clean any xfrm_if up.
v1->v2:

We return the maximum speed of all active ports. This matches how the link
speed would give an upper limit for traffic to/from any single peer if the
bridge were replaced with a hardware switch.

It is possible for a switch driver to use NET_DSA_TAG_8021Q as a valid
DSA tagging protocol since it registers itself as such, unfortunately
since there are not xmit or rcv functions provided, the lack of a xmit()
function will lead to a NPD in dsa_slave_xmit() to start with.
net/dsa/tag_8021q.c is only comprised of a set of helper functions at
the moment, but is not a fully autonomous or functional tagging "driver"
(though it could become later on). We do not have any users of
NET_DSA_TAG_8021Q so now is a good time to make sure there are not
issues being encountered by making this file strictly a place holder for
helper functions.

In commit 25b0b9c4e835 ("tipc: handle collisions of 32-bit node address
hash values"), the 32-bit node address only generated after one second
trial period expired. However the self's addr in struct tipc_monitor do
not update according to node address generated. This lead to it is
always zero as initial value. As result, sorting algorithm using this
value does not work as expected, neither neighbor monitoring framework.
In this commit, we add a fix to update self's addr when 32-bit node
address generated.

This patch adds the dataplane hardware offload to the flowtable
infrastructure. Three new flags represent the hardware state of this
flow:
* FLOW_OFFLOAD_HW: This flow entry resides in the hardware.
* FLOW_OFFLOAD_HW_DYING: This flow entry has been scheduled to be remove
from hardware. This might be triggered by either packet path (via TCP
RST/FIN packet) or via aging.
* FLOW_OFFLOAD_HW_DEAD: This flow entry has been already removed from
the hardware, the software garbage collector can remove it from the
software flowtable.
This patch supports for:
* IPv4 only.
* Aging via FLOW_CLS_STATS, no packet and byte counter synchronization
at this stage.
This patch also adds the action callback that specifies how to convert
the flow entry into the flow_rule object that is passed to the driver.
