This patch changes the internal representation of an IP address to use
struct in6_addr. IPv4 address is stored as an IPv4 mapped address.
All the functions which take an IP address as argument are also
changed to use struct in6_addr. But RDS socket layer is not modified
such that it still does not accept IPv6 address from an application.
And RDS layer does not accept nor initiate IPv6 connections.

sched: introduce chain templates support with offloading to mlxsw
For the TC clsact offload these days, some of HW drivers need
to hold a magic ball. The reason is, with the first inserted rule inside
HW they need to guess what fields will be used for the matching. If
later on this guess proves to be wrong and user adds a filter with a
different field to match, there's a problem. Mlxsw resolves it now with
couple of patterns. Those try to cover as many match fields as possible.
This aproach is far from optimal, both performance-wise and scale-wise.
Also, there is a combination of filters that in certain order won't
succeed.
Most of the time, when user inserts filters in chain, he knows right away
how the filters are going to look like - what type and option will they
have. For example, he knows that he will only insert filters of type
flower matching destination IP address. He can specify a template that
would cover all the filters in the chain.
This patchset is providing the possibility to user to provide such
template to kernel and propagate it all the way down to device
drivers.
See the examples below.
Create dummy device with clsact first:
There is no chain present by by default:
Add chain number 11 by explicit command:
chain parent ffff: chain 11
Add filter to chain number 12 which does not exist. That will create
implicit chain 12:
chain parent ffff: chain 11
chain parent ffff: chain 12
Delete both chains:
Add a chain with template of type flower allowing to insert rules matching
on last 2 bytes of destination mac address:
The chain with template is now showed in the list:
chain parent ffff: flower chain 0
dst_mac 00:00:00:00:00:00/00:00:00:00:ff:ff
eth_type ipv4
Add another chain (number 22) with template:
chain parent ffff: flower chain 0
dst_mac 00:00:00:00:00:00/00:00:00:00:ff:ff
eth_type ipv4
chain parent ffff: flower chain 22
eth_type ipv4
dst_ip 0.0.0.0/16
Add a filter that fits the template:
Addition of filters that does not fit the template would fail:
Error: cls_flower: Mask does not fit the template.
We have an error talking to the kernel, -1
Error: cls_flower: Mask does not fit the template.
We have an error talking to the kernel, -1
Additions of filters to chain 22:
Error: cls_flower: Mask does not fit the template.
We have an error talking to the kernel, -1
Error: cls_flower: Mask does not fit the template.
We have an error talking to the kernel, -1

specific chain, use this information in order to prepare a region.
Use the template to find out what elements are going to be used
and pass that down to mlxsw_sp_acl_tcam_group_add(). Later on, when the
first filter is inserted, the mlxsw_sp_acl_tcam_group_use_patterns()

that does not align with chain object exposure, creation and destruction

The cpsw has up to 4 FIFOs per port and upper 3 FIFOs can feed rate
limited queue with shaping. In order to set and enable shaping for
those 3 FIFOs queues the network device with CBS qdisc attached is
needed. The CBS configuration is added for dual-emac/single port mode
only, but potentially can be used in switch mode also, based on
switchdev for instance.
Despite the FIFO shapers can work w/o cpdma level shapers the base
usage must be in combine with cpdma level shapers as described in TRM,
that are set as maximum rates for interface queues with sysfs.

\ FIFO shaper, set with CBS offload added in this patch,
\ FIFO0 cannot be rate limited
------------------------------------------------------
CBS shaper configuration is supposed to be used with root MQPRIO Qdisc
offload allowing to add sk_prio->tc->txq maps that direct traffic to
appropriate tx queue and maps L2 priority to FIFO shaper.
The CBS shaper is intended to be used for AVB where L2 priority
(pcp field) is used to differentiate class of traffic. So additionally
vlan needs to be created with appropriate egress sk_prio->l2 prio map.
If CBS has several tx queues assigned to it, the sum of their
bandwidth has not overlap bandwidth set for CBS. It's recomended the
CBS bandwidth to be a little bit more.
The CBS shaper is configured with CBS qdisc offload interface using tc
tool from iproute2 packet.
For instance:
$ tc qdisc replace dev eth0 handle 100: parent root mqprio num_tc 3 \
map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 1
$ tc -g class show dev eth0
+---(100:ffe2) mqprio
| +---(100:3) mqprio
| +---(100:4) mqprio
|
+---(100:ffe1) mqprio
| +---(100:2) mqprio
|
+---(100:ffe0) mqprio
+---(100:1) mqprio
$ tc qdisc add dev eth0 parent 100:1 cbs locredit -1440 \
hicredit 60 sendslope -960000 idleslope 40000 offload 1
$ tc qdisc add dev eth0 parent 100:2 cbs locredit -1470 \
hicredit 62 sendslope -980000 idleslope 20000 offload 1
The above code set CBS shapers for tc0 and tc1, for that txq0 and
txq1 is used. Pay attention, the real set bandwidth can differ a bit
due to discreteness of configuration parameters.
Here parameters like locredit, hicredit and sendslope are ignored
internally and are supposed to be set with assumption that maximum
frame size for frame - 1500.
It's supposed that interface speed is not changed while reconnection,
not always is true, so inform user in case speed of interface was
changed, as it can impact on dependent shapers configuration.
For more examples see Documentation.

That's possible to offload vlan to tc priority mapping with
assumption sk_prio == L2 prio.
Example:

$ qdisc replace dev eth0 handle 100: parent root mqprio num_tc 3 \

| +---(100:4) mqprio
|
+---(100:ffe1) mqprio
| +---(100:2) mqprio
|
+---(100:ffe0) mqprio
+---(100:1) mqprio
Here, 100:1 is txq0, 100:2 is txq1, 100:3 is txq2, 100:4 is txq3
txq0 belongs to tc0, txq1 to tc1, txq2 and txq3 to tc2
The offload part only maps L2 prio to classes of traffic, but not
to transmit queues, so to direct traffic to traffic class vlan has
to be created with appropriate egress map.

The cpdma channel highest priority is from hi to lo number.
The driver has limited number of descriptors that are shared between
number of cpdma channels. Number of queues can be tuned with ethtool,
that allows to not spend descriptors on not needed cpdma channels.
In AVB usually only 2 tx queues can be enough with rate limitation.
The rate limitation can be used only for hi priority queues. Thus, to
use only 2 queues the 8 has to be created. It's wasteful.
So, in order to allow using only needed number of rate limited
tx queues, save resources, and be able to set rate limitation for
them, let assign tx cpdma channels in backward order to queues.

The tracer has one event, event 0x26, with two subtypes:
- Subtype 0: Ownership change
- Subtype 1: Traces available
An ownership change occurs in the following cases:
1- Owner releases his ownership, in this case, an event will be
sent to inform others to reattempt acquire ownership.
2- Ownership was taken by a higher priority tool, in this case
the owner should understand that it lost ownership, and go through
tear down flow.
The second subtype indicates that there are traces in the trace buffer,
in this case, the driver polls the tracer buffer for new traces, parse
them and prepares the messages for printing.
The HW starts tracing from the first address in the tracer buffer.
Driver receives an event notifying that new trace block exists.
HW posts a timestamp event at the last 8B of every 256B block.
Comparing the timestamp to the last handled timestamp would indicate
that this is a new trace block. Once the new timestamp is detected,
the entire block is considered valid.
Block validation and parsing, should be done after copying the current
block to a different location, in order to avoid block overwritten
during processing.

sh_eth: clean up the TSU register accessors
Here's a set of 5 patches against DaveM's 'net-next.git' repo. They do
a final clean up of the TSU register accessors...

sh_eth_tsu_read_entry() is still asymmetric with sh_eth_tsu_write_entry()
WRT their prototypes -- make them symmetric by passing to the former a TSU
register offset instead of its address and also adding the (now necessary)
'ndev' parameter...

We can add the TSU register base address to a TSU register offset right
in sh_eth_tsu_write_entry(), no need to do it in its callers...

With sh_eth_tsu_get_offset() now actually returning TSU register's offset,
we can at last use it in sh_eth_tsu_{read|write}(). Somehow this saves 248
bytes of object code with AArch64 gcc 4.8.5... :-)

sh_eth_tsu_get_offset(), despite its name, returns a TSU register's address,
not its offset. Make this function match its name and return a register's
offset from the TSU registers base address instead.

sh_eth_tsu_get_offset() is called several times by the driver, remove
*inline* and move that function from the header to the driver itself
to let gcc decide whether to expand it inline or not...
