Documentation: add notes for TSO & i40e
When using TSO in OVS-DPDK with an i40e device, the following
patch is required for DPDK, which fixes an issue on the TSO path:
https://patches.dpdk.org/patch/64136/
Document this as a limitation until a DPDK release with the fix
included is supported by OVS.
Also, document best known methods for performance tuning when
testing TSO with the tool iperf.
Fixes: 29cf9c1b3b9c ("userspace: Add TCP Segmentation Offload support")
