> 
> RSS expansion scheme has 2 operational modes: default and specific.
> The default mode expands into all valid options for a given network layer. For
> example, Ethernet expands by default into VLAN, IPv4 and IPv6, L3 expands
> into TCP and UDP, etc.
> The specific mode expands according to flow item next protocol
> configuration provided by the item spec and mask parameters.
> There are 3 outcomes for the specific expansion:
> 1.	Back to default – that is the case when result of (spec & mask)
> allows all possibilities.
> For example: eth type mask 0 type spec 0
> 2.	No results – in that case item configuration has no valid
> expansion. For example: eth type mask 0xffff type spec 101
> 3.	Direct - In that case flow item mask and spec configuration return
> valid expansion  option.
> Example: eth type mask 0x0fff type spec 0x0800.
> 
> Current PMD expands flow items with explicit spec and mask configuration
> into the Direct(3) or No results (2). Default expansions were handled as No
> results.
