- rename regfile_wr_idx to regfile_idx
The regfile index shall be used for both write and read operations.
Hence the field is renamed.
- remove the unused enum BNXT_ULP_REGFILE_INDEX_CACHE_ENTRY_PTR
- rename the enums in the bnxt_ulp_resource_sub_type
The enums in the bnxt_ulp_resource_sub_type are renamed to reflect
the table types explicitly.
- rename an enum in the regfile index
The BNXT_ULP_REGFILE_INDEX_ACTION_PTR_MAIN is renamed to
BNXT_ULP_REGFILE_INDEX_MAIN_ACTION_PTR since it is the main
action pointer.
- remove cache_tbl_id enums
The bnxt_ulp_cache_tbl_id enums are not required any longer
since the index is now calculated using resource sub type
and direction.

This enables using the action bitmap to update the action result
fields in the flow creation instead of using computed header fields.
Direction bit needs to be added to the action bitmap during
flow parsing, so that egress flows can be matched to the
template signature.
An example would be the usage of the vlan pop action bitmap that is
used to updated action result field as part of this commit.
Also the ulp action bitmap enumeration values that
contain open flow string are renamed.

- remove svif and VLAN info from header bitmap
The svif and vlan information are removed from header bitmap
signature so that the matching algorithm does not use these

In order to re-use allocated resources and reduce search complexity for
simple keys, a generic software cache table was added for the TCAM. The
implementation is specifically only for keys that can be compressed to
less than 16 bits. The keys are generated using the same mechanisms as
other search tables, but the table type is set to a cache that mirrors
the actual TCAM table. The allocated result fields are stored in the
cache entry and can be used for subsequent searches in future tables.

Currently, all the flow templates are sequentially searched to find out
whether there is a matching template for the incoming RTE_FLOW offload
request. As sequential search will have performance concerns, this
patch will address it by using hash algorithm to find out the flow
template. This change resulted in creation of computed fields to
remove the fields that do not participate in the hash calculations.
The field bitmap is created for this purpose.
