When classifying a packet pertaining to a given flow, the classifier
will issue multiple lookup commands until it finds one with the 'last'
bit set. It expects all prorities to be assign continuously (although
not necessarily in an ordered fashion) from 0 to the number of lookups.
We can initialize this once, and make sure unused lookups are given an
empty port map. This avoids having to maintain priorities and the
information of which lookup is the last.

The Flow Table dictates what lookups will be issued for each flow type.
The lookup sequence for each flow is similar, and the index of each
lookup is computed by some macros.
There are similar mechanisms for the C2 TCAM lookups, so in order to
avoid confusion, rename the flow table index computing macros with a
common prefix.
The only difference in behaviour is that we now use the very first entry
in the flow for the RSS lookup (the first entry was previously unused).

The classifier allows to combine multiple lookups in one "sequence" that
is counted as a single lookup to an engine, with a single result.
We don't actually use that feature, so remove any places where we set
this field, so that the classifier doesn't try to interpret these
fields.

When writing a C2 entry to hardware, some registers writes will only
take effect when the TCAM_DATA4 register is written. This includes all
C2 TCAM registers, and the C2 invalidate register.
To make sure we always write C2 entries correctly, document that
behaviour with a comment, and move TCAM writes to the end of the
mvpp2_cls_c2_write helper.

The cls_table is a global read-only table containing the different
parameters that are used by various tables in the classifier. It
describes the links between the Header Parser, the decoding table and
the flow_table.
There are several possible way we want to iterate over that table,
depending on wich classifier engine we want to configure. For the Header
Parser, we want to iterate over each entry. For the Decoding table, we
want to iterate over each entry having a unique flow_id. Finally, when
configuring an ethtool flow, we want to iterate over each entry having a
unique flow_id and that has a given flow_type.
This commit introduces some iterator to both provide syntactic sugar and
also clarify the way we want to iterate over the table.

PPv2's Classifier uses multiple engines to perform classification. So
far, only the C2 engine is used, which has a 256 entries TCAM.
So far, we only accessed the relevant entries from the C2 engines, which
are the one implementing RSS. To implement and debug ntuple
classification offload, beaing able to see the hit count for each C2
entry is helpful, so this commit moves the logic to a dedicated
directory allowing to access each entry.

The Classifier flow table is the central part of the PPv2 Classifier,
since it describes all classification steps performed for each flow.
It has 512 entries, shared between all ports, which are divided into
sequences that are pointed-to by the decoding table. Being able to see
which entries in the flow table were hit is a key point when
implementing and debugging classification offload.
This commit allows reading each flow table entry's hit count
independently, with a clear-on-read behaviour.

The current way to store the required private data needed to access
various debugfs entries is to alloc them on the fly, share them within
the entries that need to access them, and finally have one entry free
that data upon closing. This leads to hard to maintain code, and is very
error-prone.
This commit stores all debugfs related data in the same place, making
sure this is allocated only when the debugfs directory is successfully
created, so that we don't waste memory when we don't use this feature.

The cls_flow table represent the overall configuration of the

The PPv2 classifier allows to perform multiple lookups on the same
engine when classifying a packet. These lookups can match similar parts
of a packet header, but perform different actions upon matching. To
differentiate these types of lookups, it's possible to specify a Lookup
Type in the flow table entries, which will be part of the key for the
lookup engines.
This commit introduces the use of Lookup Types for C2 matches. Since for
now we only perform C2 lookups to enable RSS, we only need one Lookup
Type.

The Classifier flow table has 512 entries, that contains lookups
commands executed consecutively for every flow. Since we have 21
different flows, we have to carefully manage the flow table use.
As of today, the start index of a lookup sequence is computed
directly based in the flow->id. There are 8 reserved flow ids, from
0-7, which don't have any corresponding sequence in the flow table. We
can therefore ignore them when computing the index, and make so that the
first non-reserved flow point to the very beginning of the flow table.

Some enums in ice_tx_desc_cmd_bits have a trailing /* 2 BITS */ comment,
but the value has just one bit set (ex. ICE_TX_DESC_CMD_L4T_EOFT_SCTP

Currently the ice_q_vector structure and ice_ring_container structure
are taking up more space than necessary due to cache alignment holes
and unnecessary variables respectively. This is not helping the
driver's performance. The following fixes were done to improve cache
alignment, reduce wasted space, and increase performance.
1. Remove the ice_latency_range enum as it is unused.
2. Remove the latency_range variable in the ice_ring_container structure.
3. Change the size of the itr_idx in the ice_ring_container structure
from an int to an u16. This reduced the size of ice_ring_container
structure to 32 Bytes so it has no holes or padding.
4. Re-arrange the ice_q_vector structure using pahole to align
members as best as possible in regards to 64 Byte cache line size.

The timer should have been deleted by tipc_net_stop() when cleaning up a
netns. However, tipc has been able to enable a bearer and start d->timer
without the local node_addr set since Commit 52dfae5c85a4 ("tipc: obtain
node identity from interface by default"), which caused the timer not to
be deleted in tipc_net_stop() then.
So fix it in tipc_net_stop() by changing to check local node_id instead
of local node_addr, as Jon suggested.
While at it, remove the calling of tipc_nametbl_withdraw() there, since
tipc_nametbl_stop() will take of the nametbl's freeing after.
Fixes: 52dfae5c85a4 ("tipc: obtain node identity from interface by default")
