Add support for tunnel offload APIs. Specifically the following
are supported.
tunnel_decap_set, tunnel_match, tunnel_action_decap_release,
tunnel_item_release.

This provides support for VXLAN decap action where two flows
can indicate tunnel offload rule. The first flow indicates the
tunnel properties and second flow indicates the inner packet
structure. The templates are updated to support this
feature.

net/bnxt: cleanup ULP parser and mapper

1. Disable accum_stats for Thor
2. Delete the generic port table for default flow
3. The packet mask to calculate the number of packets must be 28 bits.
4. Increase the WC TCAM entries to 512 per application and add 2

scaling
5. Ignore multiple critical resources in ULP flow database
6. Renamed conditional code update to function opcode.
7. Updated TRUFLOW debug logs to support the above changes.
8. As part of the HA cleanup, the shared session name now allows the user
to designate that the session uses the wc_tcam regions within the
shared session.
9. The CFA action pointer does not exist if there is no support for
VF representor, so no need to display the message for use case where
there is no support for VF representors.
10. Cleanup flow counter software accumulation.
11. When an application exits ungracefully, the HA code now
clears the appropriate shared WC region and sets the HA state.
12. Removal of unnecessary INFO message. The message is an indicator that
the ports are being removed from DPDK, but all cleanup has not
completed. Once the cleanup is completed, the timer will be stopped.

net/bnxt: refactor flow parser in ULP

1. Remove Ether type, VLAN type and IP proto type from pattern matching,
since the header bits can be used for matching. This reduces the class
template signatures by a factor of 8.

2. Remove the wild card bit in the pattern matching since same template
can be used for both exact and wild card entries.

3. The action record pointers have to use higher range to not collide
with the firmware action record pointers. Hence reduced the number of
action record pointers for Whitney platform.

4. The conditional update opcode provide functionality to reject flows
for instance reject flows that do not adhere to flow signature match.

5. Added check to not populate protocol specifications if the
protocol mask is null or zero.

net/bnxt: refactor TRUFLOW processing

1. The flow database opcode is updated to split the alloc push resource
item so it can be controlled using the control table.

2. The class and action match signatures are populated with pattern ids
that are matched against template pattern id to reject any unsupported
class and action combinations.

3. The flow DB opcode should be no op when accessing the
global registry identifiers.

4. The resource function for branch is changed to control so that it
is extended to perform flow database operations and not just branch
operations.

5. The conditional goto processing now supports negative numbers to
support looping of the mapper tables to support flow ranges and
also enable conditional fail goto to support failure path mapper
tables.

6. The field mapper opcode is updated to add all ones to fields
that support exact match.

7. Added key info and identifier list to whitney action templates
The whitney plus templates are updated to use the mapper infrastructure
changes.

8. The partition interface table configuration of the default
egress rule for the representor interface needs to use the
reserved parif interface that is specific to each
platform. The pipeline for the representor interface is broken
since incorrect parif configuration cause the miss path packets to
be dropped.

9. In the mapper table processing, if a failure condition is hit
due to invalid memory type then use the conditional goto failure
configuration instead of jumping to next table. This causes ipv6
exact match entry to be skipped. This patch fixes that issue.

net/bnxt: support VXLAN decap offload

VXLAN decap offload can happen in stages. The offload request may
not come as a single flow request rather may come as two flow offload
requests F1 & F2. This patch is adding support for this two stage
offload design. The match criteria for F1 is O_DMAC, O_SMAC,
O_DST_IP, O_UDP_DPORT and actions are COUNT, MARK, JUMP. The match
criteria for F2 is O_SRC_IP, O_DST_IP, VNI and inner header fields.
F1 and F2 flow offload requests can come in any order. If F2 flow
offload request comes first then F2 can’t be offloaded as there is
no O_DMAC information in F2. In this case, F2 will be deferred until
F1 flow offload request arrives. When F1 flow offload request is
received it will have O_DMAC information. Using F1’s O_DMAC, driver
creates an L2 context entry in the hardware as part of offloading F1.
F2 will now use F1’s O_DMAC to get the L2 context id associated with
this O_DMAC and other flow fields that are cached already at the time
of deferring F2 for offloading. F2s that arrive after F1 is offloaded
will be directly programmed and not cached.
