[dpdk-dev] [PATCH] app/testpmd: support unequal number of RXQ and TXQ

[nipun.gupta at nxp.com]

From: Jun Yang <jun.yang at nxp.com>

The existing forwarding mode configures the total number of
queues as the minimum of rxq and txq, so eventually the number
of txq are same as rxq.
However in some scenarios, specially for flow control the
number of rxq and txq can be different.
This patch makes the txq and function of rxq for all such
scenario instead of keeping 1:1 relationship between the two.
