[dpdk-dev] reassembly app doesn't send pkt

[Victor Detoni]

Hi,

When I test ip_reassembly app on vmxnet3 nic works fine, but when I change
to the nics 82599ES 10-Gigabit  SFI/SFP+, it stop to send the packet
"reassembled" on tx nic.

when I remove the code bellow on rte_ipv4_reassembly.c source code, it
sends pkt but truncated.

rte_pktmbuf_chain(fp->frags[IP_FIRST_FRAG_IDX].mb, m);

Anybody has some tip? I printed all functions like send_single_packet and
send_burst and it seems Ok, when I compare ping pkt and udp frag pkt.

Hi,

I have the same problem using 82599. When I sent a mbuf with multi-segment,
the 82599 driver's tx_burst fuction
will return 0, which means no packet sent.

I have no solution. Some 82599 NICs can send these packet successfully, but
some will fail.
?? I think this problem may related to vendor or firmware.
