=> Actually, the fact that eviction happens during your tests implies
=> that you should increase eviction threshold (ipfrag_high_thresh)
=> to value, when eviction never happens on LAN tests. It should happen
=> only if driver has lost some fragment... not good on LAN too.
Is there a counter telling me when "eviction happens"?
