The current DPDK hash library does not support this, unfortunately. There is currently an effort underway to do a cuckoo hash implementation for DPDK (patches already on-list), to allow items to move between buckets rather than just failing if a bucket is full. Please feel free to try out these patches and provide feedback on them if you can! /Bruce >
