Message-ID: <20190813020730.10038-2-tiwei.bie@intel.com> (raw)
In-Reply-To: <20190813020730.10038-1-tiwei.bie@intel.com>

The simple Tx path in virtio has been removed in below commit.
This patch removes an undefined function declaration of simple
Tx and all related descriptions in the doc.

Fixes: 57f818963d80 ("net/virtio: remove simple Tx path")

 Vector callbacks will be used when:
 
-*   ``txmode.offloads`` is set to ``0x0``, which implies:
-
-    *   Single segment is specified.
-
-    *   No offload support is needed.
-
 *   Mergeable Rx buffers is disabled.
 
 The corresponding callbacks are:
 
 *   For Rx: ``virtio_recv_pkts_vec``.
 
-*   For Tx: ``virtio_xmit_pkts_simple``.

 Example of using the vector version of the virtio poll mode driver in
 ``testpmd``::
 
-   testpmd -l 0-2 -n 4 -- -i --tx-offloads=0x0 --rxq=1 --txq=1 --nb-cores=1
+   testpmd -l 0-2 -n 4 -- -i --rxq=1 --txq=1 --nb-cores=1
 
 In-order callbacks only work on simulated virtio user vdev.
