[dpdk-dev] [PATCH] testpmd: print message if starting/stopping queue is not supported

["Nicolás Pernas Maradei" <nico@emutex.com>]

Print an error message to the user when trying to start/stop a rx/tx queue and
this function is not supported by the PMD driver. The patch does not check if
the return value is -EINVAL because testpmd is already validating the port and
queue id.
