- DPDK v17.11 virtio PMD contains a bug in the vectorized Rx function that
- affects testpmd/DPDK guest applications. As such, guest DPDK applications
- should use a non-vectorized Rx function.
-
-The DPDK v17.11 virtio net driver contains a bug that prevents guest DPDK
-applications from receiving packets when the vectorized Rx function is used.
-This only occurs when guest-bound traffic is live before a DPDK application is
-started within the guest, and where two or more forwarding cores are used. As
-such, it is not recommended for guests which execute DPDK applications to use
-the virtio vectorized Rx function. A simple method of ensuring that a non-
-vectorized Rx function is used is to enable mergeable buffers for the guest,
-with the following QEMU command line option::
-
- mrg_rxbuf=on
