samples: pktgen: new append mode
To configure various complex flows we for sure can create custom pktgen init scripts, but sometimes thats not that easy. New "-a" (append) option in all the existing sample scripts allows to append more "devices" into pktgen threads. The most straightforward usecases for that are: - using multiple devices. We have to generate full linerate on all physical functions (ports) of our multiport device. - pushing multiple flows (with different packet options) Signed-off-by: Igor Russkikh <irusskikh@marvell.com> Signed-off-by: David S.
