Hi David,

Thanks for the notice.

>From logic this looks like a false positive.. The only way I found to eliminate the
warning is

--- a/app/test-pmd/flowgen.c
+++ b/app/test-pmd/flowgen.c
@@ -85,7 +85,7 @@ pkt_burst_flow_gen(struct fwd_stream *fs)
        unsigned pkt_size = tx_pkt_length - 4;  /* Adjust FCS */
        struct rte_mbuf  *pkts_burst[MAX_PKT_BURST];
        struct rte_mempool *mbp;
-       struct rte_mbuf  *pkt;
+       struct rte_mbuf  *pkt = NULL;

Its abit dumb, but still.

Will resubmit.

Thanks,
  Igor
