Many of the bond param variables are declared global while it's not
really necessary for these variables to be global. So moving them to
the location these are used.

LACP state-machine defines "port-moved" state when the same ActorSystemID
and Port are seen in a LACPDU received on different port. The state is
never set since it's not implemented. However the state-machine attempts
to clear that state occasionally. LACP state machine is already complicated
and since this state is not implemented, removing it's checks makes the
state-machine little simpler.

Initializing work-queues every time ifup operation performed is unnecessary
and can be performed only once when the port is created.

In preparation to move the work-queue initialization to port creation
from current port_open phase. Work-queue initialization does not make
sense every time we do 'ifup/ifdown'. So moving to port creation phase.
Arp monitoring work depends on the bonding mode and that is not tied
to the port creation and can change anytime during the life after port
creation. So this restructuring allows us to move the initialization
at creation without losing the ability to arm the correct work for the
mode user has selected.

Prevent theoretical buffer overrun by returning an error if
the number of entries returned by the firmware does not match those
present.
Also use a common handling error path.

We only need FW version in the first cache line of adapter struct
because we need to know the metadata format. To save space add a
metadata format bit.

We really only need the device pointer on the fast path, stash it at
the beginning of the adapter structure and move pci_dev pointer down.
This saves up a few lines of code.

NSP reports to us port labels. First id is the id of the physical
port, the other one tells us which logical interface is it within a
split port. Instead of printing them as string keep them in integer
format. Compute which interfaces are part of port split.
On netdev side use port labels and split information to provide a
.ndo_get_phys_port_name() implementation. We follow the name format
of mlxsw which is also suggested in "Port Netdev Naming" section
of Documentation/networking/switchdev.txt.

Some firmware images may reuse CRC32 hardware to compute RXHASH.
Make sure we report the correct hash function. Note that we don't
support changing functions at runtime. That would also require
a few more additions to the way the key is set because different
functions have different key sizes.

Currently the sock queue's spin locks get their lockdep
classes by the default init_spin_lock() initializer:
all socket families get - usually, see below - a single
class for rx, another specific class for tx, etc.
This can lead to false positive lockdep splat, as
reported by Andrey.
Moreover there are two separate initialization points
for the sock queues, one in sk_clone_lock() and one
in sock_init_data(), so that e.g. the rx queue lock
can get one of two possible, different classes, depending
on the socket being cloned or not.
This change tries to address the above, setting explicitly
a per address family lockdep class for each queue's
spinlock. Also, move the duplicated initialization code to a
single location.
v1 -> v2:
- renamed the init helper
rfc -> v1:
- no changes, tested with several different workload

Synopsys provides a new DesignWare Core Enterprise Ethernet MAC
IP (DWC-XLGMAC) for Ethernet designs. It is compliant with the
IEEE 802.3-2012 specifications, including IEEE 802.3ba and
consortium specifications.
This patch provides the initial 25G/40G/50G/100G Ethernet driver
for Synopsys XLGMAC IP Prototyping Kit.
