[PATCH] net/memif: fix buffer overflow in zero copy Rx

ption and duplicate mbufs being received. Allocate 2x the space for the mbuf ring, so that the alloc function has a contiguous array to write to, then copy the excess entries to the start of the array. Fixes: 43b815d88188 ("net/memif: support zero-copy slave") Cc: sta...@dpdk.org Signe
