>Define dummy packet headers to allow adding advanced rules in HW. This
>header is used as admin queue command parameter for adding a rule.
>The firmware will extract correct fields and will use them in look ups.
>Define each supported packets header and offsets to words used in recipe.
>Supported headers:
>- MAC + IPv4 + UDP
>- MAC + VLAN + IPv4 + UDP
>- MAC + IPv4 + TCP
>- MAC + VLAN + IPv4 + TCP
>- MAC + IPv6 + UDP
>- MAC + VLAN + IPv6 + UDP
>- MAC + IPv6 + TCP
>- MAC + VLAN + IPv6 + TCP
>Add code for creating an advanced rule. Rule needs to match defined dummy
>packet, if not return error, which means that this type of rule isn't currently
>The first step in adding advanced rule is searching for an advanced recipe
>matching this kind of rule. If it doesn't exist new recipe is created. Dummy
>packet has to be filled with the correct header field value from the rule
>definition. It will be used to do look up in HW.
>Support searching for existing advance rule entry. It is used in case of adding
>the same rule on different VSI. In this case, instead of creating new rule, the
>existing one should be updated with refreshed VSI list.
>Add initialization for prof_res_bm_init flag to zero so that the possible
>resource for fv in the files can be initialized.
