> To provide the better PCIe bandwidth utilization the ConnectX-4LX NIC
> supports the multi-packet write (MPW) sessions allowing to pack multiple
> packets into one descriptor (WQE). This is legacy feature and it has some
> limitations on the packets and data description segments. To provide the
> best performance all inline packets must be put into shared data segment
> and the total length of MPW session must be limited. The limit is controlled
> with txq_inline_mpw devarg.
