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
