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.

Virtio PMD Rx/Tx Callbacks

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.
