Hi ,every one
when I was conducting nic offloading exp,I can not make a x520 nic insert
vlan ,nor checksum,
here is my rx/tx capability:
rx offload capability:9f
tx offload capability:203f
with code like this:
while(1){
nr_mbufs=rte_eth_rx_burst(0,queue_id,mbufs,32);
for(idx=0;idx<nr_mbufs;idx++){
#if 0
buffer=rte_pktmbuf_mtod(mbufs[idx],char*);
ip4=(struct ipv4_hdr*)(buffer+14);
ip4->hdr_checksum=0;
mbufs[idx]->l2_len=14;
mbufs[idx]->l3_len=20;
mbufs[idx]->ol_flags=PKT_TX_IP_CKSUM|PKT_TX_IPV4;
#else
mbufs[idx]->vlan_tci=0xef00;
mbufs[idx]->ol_flags=PKT_TX_VLAN_PKT;
#endif
rte_eth_tx_burst(0,queue_id,&mbufs[idx],1);
}
}
does anybody know what;s wrong with my code?
Thanks & regards
Linc
