udp: Fix multicast performance issues.
Fix performance issues with listening to many different multicast
sockets on different addresses with the same port. Instead of always
using hash1, fall back to hash2 lookup when hash1 lookup is long.
Patch 1 is a general cleanup and simplification which also makes the
main implementation in Patch 2 simpler.
Eric's recent change 63c6f81cdd avoided this being an issue in early
demux. This makes it work for regular delivery as well.

Many multicast sources can have the same port which can result in a very
large list when hashing by port only. Hash by address and port instead
if this is the case. This makes multicast more similar to unicast.
On a 24-core machine receiving from 500 multicast sockets on the same
port, before this patch 80% of system CPU was used up by spin locking
and only ~25% of packets were successfully delivered.
With this patch, all packets are delivered and kernel overhead is ~8%
system CPU on spinlocks.

When we run broadcast packets over dual bearers/interfaces, the
current transmission code is flipping bearers between each sent
packet, with the purpose of leveraging the double bandwidth
available. The receiving bclink is resequencing the packets if
needed, so all messages are delivered upwards from the broadcast
link in the correct order, even if they may arrive in concurrent
interrupts.
However, at the moment of delivery upwards to the socket, we release
all spinlocks (bclink_lock, node_lock), so it is still possible
that arriving messages bypass each other before they reach the socket
queue.
We fix this by applying the same technique we are using for unicast
traffic. We use a link selector (i.e., the last bit of sending port
number) to ensure that messages from the same sender socket always are
sent over the same bearer. This guarantees sequential delivery between
socket pairs, which is sufficient to satisfy the protocol spec, as well
as all known user requirements.

This gives a shorter and simpler code path, and makes it possible

simply passes the sctp_sndinfo structure (defined in Section 5.3.4)
to this call. The input parameters accepted by this call include
snd_sid, snd_flags, snd_ppid, and snd_context. The snd_flags
parameter is composed of a bitwise OR of SCTP_UNORDERED, SCTP_EOF,

to which to apply the parameters. For a one-to-many style socket,

skb_tx_timestamp() does not report software time stamp
if SKBTX_IN_PROGRESS is set. According to timestamping.txt
software time stamps are a fallback and should not be
generated if hardware time stamp is provided.
Move call to skb_tx_timestamp() after setting
SKBTX_IN_PROGRESS.

This patch adds a new API to get the port mac address from firmware.
It also adds support to the ndo_get_phys_port_id() callback to provide
port specific unique id to the netdev layer.
If the adapter has a valid per-port mac address then that
would be used for this purpose and is expected to be unique
on a per-port basis.
The information can be viewed by reading the phys_port_id
attribute in sysfs for each netdev or via IF netlink
interface.

Things seem to calm down so far, just a small few HD-audio fixes
(regression fixes and a new codec ID addition) popping up.

OPPs can be populated statically, via DT, or added at run time with
dev_pm_opp_add().
While this driver handles the first case correctly, it would fail to populate
OPPs added at runtime. Because call to of_init_opp_table() would fail as there
are no OPPs in DT and probe will return early.
To fix this, remove error checking and call dev_pm_opp_init_cpufreq_table()
unconditionally.
Update bindings as well.

Commit ff1f0018cf ("drivers: Enable
building of Kirkwood drivers for mach-mvebu") added Kirkwood into
mach-mvebu, adding MACH_KIRKWOOD to ARCH_KIRKWOOD in the KConfig files.
The change for ARM_KIRKWOOD_CPUFREQ replaced ARCH_KIRKWOOD with
MACH_KIRKWOOD, whereas all the other changes were ARCH_KIRKWOOD ||
MACH_KIRKWOOD.
As a consequence of this change, the cpufreq driver is no longer enabled
for ARCH_KIRKWOOD. This patch reinstates ARM_KIRKWOOD_CPUFREQ for
ARCH_KIRKWOOD.
