Ok...I think you meant there's a bug in the driver code when formatting
multi-segment mbuf.

On my setup, the sending host is a regular one without running dpdk. It
sends out 2500-byte packet without fragmentation to the dpdk node.
Isn't it the enic pmd driver that is responsible for fetch the packet and
format the mbuf (or mbuf chain if required)? Or do you mean I need to write
my own co

It is a bug in the creator of the mbuf, if number of segments and next
chain don't
match.
There is a rte_pktmbuf_dump(), you can use to look at how your mbuf is
formatted.

Sorry my bad. The mbuf size has been accidentally changed to 3000.
After fixing this by setting mbuf size to 2048, multi-segment mbuf still
doesn't work. I was trying to send 2500-byte packets to the target system
and was expecting to see two-segment mbuf chain), but got errors on it.

I am trying multi-segment mbuf, but it seems not working.
On my target host, the mbuf size is set to 2048 and I am trying to send
large packet to it (say 2500 bytes without fragmentation) from another
host. I enabled both jumbo_frame and enable_scatter for the port. But I saw
on the target only on
