Kristof Provost 5a3b9507d7 pf: Convert pfi_kkif to use counter_u64 
Improve caching behaviour by using counter_u64 rather than variables
shared between cores.

The result of converting all counters to counter(9) (i.e. this full
patch series) is a significant improvement in throughput. As tested by
olivier@, on Intel Xeon E5-2697Av4 (16Cores, 32 threads) hardware with
Mellanox ConnectX-4 MCX416A-CCAT (100GBase-SR4) nics we see:
