[dpdk-users] Frame Check Sequence is incorrect?

[waqas ahmed]

Hi Everyone,
i have kvm with two ports, i am getting rtp stream from port 0 and just
change source ip of each packet and recalculate ipv4 checksum. then same
pkt mbuf is got rte_eth_tx_burst from port1.
but on vm2 wireshark shows that Frame check sequence is incorrect, that
seems that while getting same mbuf out from port1 cant get FCS
recalculated? by emulated nic.
kind regards and any help is appreciated.
