legacy code accepts patterns with non null spec/mask containing all

priority = RTE_MIN(IXGBE_MAX_N_TUPLE_PRIO, 
RTE_MAX(IXGBE_MIN_N_TUPLE_PRIO, attr->priority))

otherwise priority 0 maps to 7

I'm not sure we need to copy from the flow if the corresponding mask is 
set. For example, in ixgbe_process_ntuple_ipv4(), dst_ip is copied from 
an item independently of the mask. Thus, a user may install two or more 
semantically identical rules with different values in masked-out fields 
and consume all available filters.
