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. 2016-11-12 21:29 GMT+08:00 Victor Detoni <victordet...@gmail.com>: > 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?
