This works fine -- thanks. > Also TX may have per-slot limitations (e.g. due to the size of the NIC > TX fifo), but this is usually > 9K, so using a single descriptor per > packet should always > be ok. However, you can also use multiple slots on the TX side (see > utils/functional.c::tx_one()). Trying to split TX frames into multiple buffers does not work, the NIC is sending 2048 byte frames (the buf_size I am using). I will re-check my code. Do I need a particular version of ixgbevf perhaps?
