Hi Wenzhuo,

Thanks. For some reason, we have to stick to dpdk 2.0 for now. Is multi-segment
mbuf supported in this version (any known issue with multi-seg in this version?)
or do we have to upgrade to latest dpdk version for multi-segment support?

Yes, I suggest to try at least 2.1.  It should help.
And to my opinion, the newer the better. As you know there'll be more functions and less bugs :)

ixgbe_recv_scattered_pkts was set to be the rx function. Receiving
packets

I see this function is already deprecated. Do you use an old version? Would

you like to try the newest code?

smaller than mbuf size works perfectly. However, if an incoming
packet is greater than the maximum acceptable length of one "mbuf"
data size, receiving does not work. In this case, isn't it supposed to use mbuf

chaining to receive?

The port has both jumbo_frame and enable_scatter being on. are these
two flags good enough to make mbuf chaining going?
