[dpdk-dev] [PATCH 3/3] app/testpmd: use of Rx/Tx in testpmd

[Lijun Ou <oulijun@huawei.com>]

From: Hongbo Zheng <zhenghongbo3@huawei.com>

In testpmd, when we input "show config rxtx", we can see like this:

1: testpmd> show config rxtx
2:   io packet forwarding packets/burst=32
3:   nb forwarding cores=1 - nb forwarding ports=1
4:   port 0: RX queue number: 1 Tx queue number: 1
5:     Rx offloads=0x0 Tx offloads=0x10000
6:     RX queue: 0
7:       RX desc=1024 - RX free threshold=32
8:       RX threshold registers: pthresh=0 hthresh=0  wthresh=0
9:       RX Offloads=0x0
10:    TX queue: 0
11:      TX desc=1024 - TX free threshold=928
12:      TX threshold registers: pthresh=0 hthresh=0  wthresh=0
13:      TX offloads=0x10000 - TX RS bit threshold=32

We can see RX/Rx/TX/Tx is mixed used. Also in other places in testpmd,
RX/Rx/TX/Tx is mixed used.

This patch fix the mixed use of RX/Rx/TX/Tx in testpmd by change
to unified use Rx/Tx.
