[dpdk-dev] [PATCH] app/testpmd: update start log to be less verbose

[Ferruh Yigit <ferruh.yigit@intel.com>]

A per port per queue log is too verbose with multiple port/queue log is
longer than full screen, make it less verbose:
- Reduced log to only first queue of the port, as a sample
- Merged a few lines
- Indent queue logs for readability

The log becomes as following after update:

testpmd> start tx_first
io packet forwarding - ports=2 - cores=1 - streams=8 - NUMA support enabled, MP over anonymous pages disabled
Logical Core 1 (socket 0) forwards packets on 8 streams:
  RX P=0/Q=0 (socket 0) -> TX P=1/Q=0 (socket 0) peer=02:00:00:00:00:01
  RX P=0/Q=1 (socket 0) -> TX P=1/Q=1 (socket 0) peer=02:00:00:00:00:01
  RX P=0/Q=2 (socket 0) -> TX P=1/Q=2 (socket 0) peer=02:00:00:00:00:01
  RX P=0/Q=3 (socket 0) -> TX P=1/Q=3 (socket 0) peer=02:00:00:00:00:01
  RX P=1/Q=0 (socket 0) -> TX P=0/Q=0 (socket 0) peer=02:00:00:00:00:00
  RX P=1/Q=1 (socket 0) -> TX P=0/Q=1 (socket 0) peer=02:00:00:00:00:00
  RX P=1/Q=2 (socket 0) -> TX P=0/Q=2 (socket 0) peer=02:00:00:00:00:00

Hi Qi,

If you are agree with the patch I can squash into original patch.

btw, desc numbers are zero, "TX desc=0","RX desc=0", is this correct?
