> Existing code to create shared RSS action doesn't fully check
> driver capabilities.
> Using older driver, if DevX capabilities are insufficient,
> the IBV operations are used.
> In this case the ind_table_modify operation is not supported, and
> shared RSS action can't be modified after creation.
> This patch adds check of driver capability, and fails the validation
> for shared RSS action in case it is insufficient.
