Hi,
When I enable the Tx offloads capabilities, I get the segmentation fault.
The backtrace like this:
lcore_main_loop
--> main_loop_tx
--> rte_eth_tx_burst
--> eth_igb_xmit_pkts
--> rte_pktmbuf_free_seg
--> rte_pktmbuf_prefree_seg
--> rte_pktmbuf_detach
--> __rte_pktmbuf_free_extbuf
--> rte_mbuf_ext_refcnt_update
--> rte_mbuf_ext_refcnt_read
--> rte_atomic16_read
return v->cnt;
And I set Tx offloads like this:
.txmode = {
.mq_mode = ETH_MQ_TX_NONE,
.offloads = DEV_TX_OFFLOAD_IPV4_CKSUM | \
DEV_TX_OFFLOAD_TCP_CKSUM | \
DEV_TX_OFFLOAD_UDP_CKSUM
},
and set the m->ol_flags, l2_len, l3_len and l4_len.
Is there something I am missing? The NIC is Intel Corporation I350 Gigabit Network Connection(rev 01).
Thanks in advance.
