it seems that set fdir port conf cause the problem,just add fdir conf
in the port_conf, don't add any fdir rules.
set port conf like this in the l2fwd code.
static const struct rte_eth_conf port_conf = {
.rxmode = {
.split_hdr_size = 0,
.header_split = 0,
The issue can be reproduced with example program l2fwd by modifying it
to sleep 1 second before launching thread.
code like this:
check_all_ports_link_status(nb_ports, l2fwd_enabled_port_mask);
sleep(1);
/* launch per-lcore init on every lcore */
rte_
The rx function used was ixgbe_recv_pkts_bulk_alloc.
the problem seems that the rx desc ring not full, but nic don't write
data to ring and inc the missed error counter.
