SMC code uses the base gid for VLAN traffic. The gids exchanged in
the CLC handshake and the gid index used for the QP have to switch
from the base gid to the appropriate vlan gid.
When searching for a matching IB device port for a certain vlan
device, it does not make sense to return an IB device port, which
is not enabled for the used vlan_id. Add another check whether a
vlan gid exists for a certain IB device port.

nfp: protect from theoretical size overflows and SR-IOV errors
This small set changes the handling of pci_sriov_set_totalvfs() errors.
nfp is the only driver which fails probe on pci_sriov_set_totalvfs()
errors. It turns out some BIOS configurations may break SR-IOV and
users who don't use that feature should not suffer.
Remaining patches makes sure we use overflow-safe function for ring
allocation, even though ring sizes are limited. It won't hurt and
we can also enable fallback to vmalloc() if memory is tight while
at it.

we may not be able to set the SR-IOV VF limit in sysfs, it's not fatal

mlxsw: Introduce algorithmic TCAM support
The Spectrum-2 ASIC uses an algorithmic TCAM (A-TCAM) where multiple
exact matches lookups are performed instead of a single lookup as with
standard circuit TCAM (C-TCAM) memory. This allows for higher scale and
reduced power consumption.
The lookups are performed by masking a packet using different masks
(e.g., {dst_ip/24, ethtype}) defined for the region and looking for an
exact match. Eventually, the rule with the highest priority will be
picked.
Since the number of masks per-region is limited, the ASIC includes a
C-TCAM that can be used as a spill area for rules that do not fit into
the A-TCAM.
The driver currently uses a C-TCAM only mode which is similar to
Spectrum-1. However, this mode severely limits both the number of
supported ACL rules and the performance of the ACL lookup.
This patch set introduces initial support for the A-TCAM mode where the
C-TCAM is only used for rule spillage.
The first five patches add the registers and ASIC resources needed in
order to make use of the A-TCAM.
Next three patches are the "meat" and add the eRP core which is used to
manage the masks used by each ACL region. The individual commit messages
are lengthy and aim to thoroughly explain the subject.
The next seven patches perform small adjustments in the code and the
related data structures and are meant to prepare the code base to the
introduction of the A-TCAM in the last two patches.
Various A-TCAM optimization will be the focus of follow-up patch sets:
* Pruning - Used to reduce the number of lookups. Each rule will include
a prune vector that indicates which masks should not be considered for
further lookups as they cannot result in a higher priority match
* Bloom filter - Used to reduce the number of lookups. Before performing
a lookup with a given mask the ASIC will consult a bloom filter
(managed by the driver) that indicates whether a match might exist using
the considered mask
* Masks aggregation - Used to increase scale and reduce lookups. Masks
that only differ by up to eight consecutive bits (delta bits) can be
aggregated into a single mask. The delta bits then become a part of the
rule's key. For example, dst_ip/16 and dst_ip/17 can be represented as
dst_ip/16 with a delta bit of one. Rules using the aggregated mask then
specify whether the 17-th bit should be masked or not and its value

Implement rule insertion and deletion into the A-TCAM before we flip the
driver to start using the A-TCAM.
Rule insertion into the A-TCAM is very similar to C-TCAM, but there are
subtle differences between regions of different sizes (i.e., different
number of key blocks).
Specifically, as explained in "mlxsw: spectrum_acl: Allow encoding a
partial key", in 12 key blocks regions a rule is split into two and the
two halves of the rule are linked using a "large entry key ID".
Such differences are abstracted away by using different region
operations per region type.

When A-TCAM will be used together with C-TCAM, the C-TCAM code will need
to call into the eRP core in order to get an eRP for an inserted entry.
The eRP core takes an A-TCAM region as one of its arguments, so pass the
C-TCAM region to the insertion function which will later allow us to
derive the A-TCAM region, given it contains the C-TCAM one.

Each TCAM region currently uses its own resources and there is no
sharing between the different regions.
This is going to change with A-TCAM as each region will need to allocate
an eRP table from the global eRP tables array.

TCAM private data to the region initialization routine.

In Spectrum-2 the C-TCAM is only used for rules that can't fit in the
A-TCAM due to a limited number of masks per A-TCAM region.
In addition, rules inserted into the C-TCAM may affect rules residing in
the A-TCAM, by clearing their C-TCAM prune bit.
The two regions are thus closely related and can be thought of as if the
C-TCAM region is encapsulated in the A-TCAM one.
Change the data structures to reflect that before introducing A-TCAM
support and make C-TCAM region initialization part of the A-TCAM region
initialization sequence.

When working with 12 key blocks in the A-TCAM, rules are split into two
records, which constitute two lookups. The two records are linked using
a "large entry key ID". The ID is assigned to key blocks 6 to 11 and
resolved during the first lookup. The second lookup is performed using
the ID and the remaining key blocks.
Allow encoding a partial key so that it can be later used to check if an
ID can be reused.
This is done by adding two arguments to the existing encode function
that specify the range of the block indexes we would like to encode. The
key and mask arguments become optional, as we will not need to encode
both of them all the time.

The number of eRPs that can be used by a single A-TCAM region is limited
to 16. When more eRPs are needed, an ordinary circuit TCAM (C-TCAM) can
be used to hold the extra eRPs.
Unlike the A-TCAM, only a single (last) lookup is performed in the
C-TCAM and not a lookup per-eRP. However, modeling the C-TCAM as extra
eRPs will allow us to easily introduce support for pruning in a
follow-up patch set and is also logically correct.
The following diagram depicts the relation between both TCAMs:
C-TCAM
+-------------------+ +--------------------+ +-----------+
| | | | | |
| eRP #1 (A-TCAM) +----> ... +----+ eRP #16 (A-TCAM) +----+ eRP #17 |
| | | | | ... |
+-------------------+ +--------------------+ | eRP #N |
| |
+-----------+
Lookup order is from left to right.
Extend the eRP core APIs with a C-TCAM parameter which indicates whether
the requested eRP is to be used with the C-TCAM or not.
Since the C-TCAM is only meant to absorb rules that can't fit in the
A-TCAM due to exceeded number of eRPs or key collision, an error is
returned when a C-TCAM eRP needs to be created when the eRP state
machine is in its initial state (i.e., 'no masks'). This should only
happen in the face of very unlikely errors when trying to push rules
into the A-TCAM.
In order not to perform unnecessary lookups, the eRP core will only
enable a C-TCAM lookup for a given region if it knows there are C-TCAM
eRPs present.

When rules are inserted into the A-TCAM they are associated with a mask,
which is part of the lookup key: { masked key, mask ID, region ID }.
These masks are called rule patterns (RP) and the aggregation of several
masks into one (to be introduced in follow-up patch sets) is called an
extended RP (eRP).
When a packet undergoes a lookup in an ACL region it is masked by the
current set of eRPs used by the region, looking for an exact match.
Eventually, the rule with the highest priority is picked.
These eRPs are stored in several global banks to allow for lookup to
occur using several eRPs simultaneously.
At first, an ACL region will only require a single mask - upon the
insertion of the first rule. In this case, the region can use the
"master RP" which is composed by OR-ing all the masks used by the
region. This mask is a property of the region and thus there is no need
to use the above mentioned banks.
At some point, a second mask will be needed. In this case, the region
will need to allocate an eRP table from the above mentioned banks and
insert its masks there.
>From now on, upon lookup, the eRP table used by the region will be
fetched from the eRP banks - using {eRP bank, Index within the bank} -
and the eRPs present in the table will be used to mask the packet. Note
that masks with consecutive indexes are inserted into consecutive banks.
When rules are deleted and a region only needs a single mask once again
it can free its eRP table and use the master RP.
The above logic is implemented in the eRP core and represented using the
following state machine:
+------------+ create mask - as master RP +---------------+
| +--------------------------------> |
| no masks | | single mask |
| <--------------------------------+ |
+------------+ delete mask +-----+--^------+
| |
| |
create mask - | | delete mask -
create mask transition to use eRP | | transition to
+--------+ table | | use master RP
| | | |
| | | |
+----v--------+----+ create mask +----v--+-----+
| <-------------------------------+ |
| multiple masks | | two masks |
| +-------------------------------> |
+------------------+ delete mask - if two +-------------+
remaining
The code that actually configures rules in the A-TCAM will interface
with the eRP core by getting or putting an eRP based on the required
mask used by the rule.
