[dpdk-stable] [PATCH 19.11] app/testpmd: fix usage text

[Thomas Monjalon <thomas@monjalon.net>]

[ upstream commit c6d527a1c8bdee9435ce150670acf1657234c0c1 ]

The options help text was including an incomplete and redundant
summary of the options before explaining each. The summary is dropped.

There were some mismatches between options in the usage text
	sed -rn 's/.*\(" *--([a-z-]*)[=: ].*/\1/p' app/test-pmd/parameters.c
and the options declared in lgopts array
	sed -rn 's/.*\{.*"(.*)",.*,.*,.*},.*/\1/p' app/test-pmd/parameters.c
The misses were:
	--no-numa
	--enable-scatter
	--tx-ip
	--tx-udp
	--noisy-lkup-num-reads-writes
The option --ports was not implemented.

Fixes: 3c156061b938 ("app/testpmd: add noisy neighbour forwarding mode")
Fixes: bf5b2126bf44 ("app/testpmd: add ability to set Tx IP and UDP parameters")
Fixes: 0499793854f5 ("app/testpmd: add scatter enabling option")
Fixes: 999b2ee0fe45 ("app/testpmd: enable NUMA support by default")
Fixes: af75078fece3 ("first public release")
