1. Added support to specify l4 port masks in the template. Also enabled

2. Added support to enable offload for ipv6 traffic within the vxlan
tunnel connection.

3. The flow counters is reduced from 7168 to 6912 for Whitney.
The stats operation is updated to reflect counts for packets
at egress from CFA instead of ingress to CFA

4. The miss path for the l2 context table is updated with correct
parif and default action handler to handle the miss path for
egress flows.

5. This support enables allocation of encapsulation, modification and
action records dynamically based on a given flow actions.

6. Reduce the l2context resource requests during open_session. Move the
SMAC from the L2Context to the EM/WM

7. Remap the parif in the bd action in order to eliminate incorrect
replication of broadcast packets. The layer 4 source port mask
was incorrectly updated in the outer layer 4 source port mask
instead of inner layer 4. Add the l3 proto to egress rules, switch
to using computed fields for l4 ports, add internal smac to f1/f2

net/bnxt: process resource lists before session open

Shared sessions require both named and unnamed resources to be requested
during a tf_open_session. ULP uses named resources for global resources
that are pre-allocated and remain through the life of the application.
Unnamed resources are generally per flow resources and allocated on
demand. The sum of both named and unnamed resources must be requested
when initializing the session. The ulp_init now processes both lists
prior to calling tf_open_session for both shared and regular sessions.

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.

6. Check that field array is not overrun.

net/bnxt: refactor ULP mapper

1. The internal and external exact match table resource types
is combined since the resource handle contains the encoded
type whether it is internal or external exact match entry.

2. When a flow doesn't hit the offloaded rules, the default action is
to send it to the kernel (L2 driver interface). In order to do that,
TRUFLOW must know the kernel interface's (PF's) default vnic id.
This patch fetches the PF's default vnic id from the dpdk core and
stores it in port database. It also stores the mac addr for the
future usage. Renamed compute field for layer 4 port enums.
Added support for port database opcode that can get port details
like mac address which can then be populated in the l2 context entry.

3. Both active and default bit set need to considered to check if a
specific flow type is enabled or not.

4. ulp mapper fetches the dpdk port id from the compute field index
BNXT_ULP_CF_IDX_DEV_PORT_ID which is used to get the interface’s
mac address eventually. However, the compute field array is not
populated with dpdk port id at the index BNXT_ULP_CF_IDX_DEV_PORT_ID.
The problem fixed by populating the compute field array correctly.

5. Some dpdk applications may accumulate the flow counters while some
may not. In cases where the application is accumulating the counters
the PMD need not do the accumulation itself and viceversa to report
the correct flow counters.

6. Pointer to bp is added to open session parms to support
shared session.

2. The class and action match signatures are populated with pattern ids

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.
