[dpdk-dev] [PATCH v5 3/3] app/testpmd: add a command to add many MAC addrs

[Wei Dai <wei.dai@intel.com>]

This patch is added to introduce a testpmd command which
is used to add more than one MAC addresses one time.
This command can simplify the test for the change where
the type of return value of adding MAC address.
Normally a MAC address may fails to be added only after
many MAC addresses have been added.
Without this command, a tester may only trigger failed
MAC address by running many times of testpmd command
'mac_addr add' .
