dpdk: bump to dpdk 19.02
HQoS requires fixes to work with dpdk 19.02 so code is disabled and pending deprecation unless active maintainer is found. Change-Id: I3569c4287b6dfdd2c29e02375eb53bf01fa6ae84 Signed-off-by: Damjan Marion <damarion@cisco.com>

-Subject: [PATCH] net/ena: recreate HW IO rings on start and stop
-
-On the start the driver was refilling all Rx buffs, but the old ones
-were not released. That way running start/stop for a few times was
-causing device to run out of descriptors.
-
-To fix the issue, IO rings are now being destroyed on stop, and
-recreated on start. That is way the device is not losing any
-descriptors.
-
-Furthermore, there was also memory leak for the Rx mbufs, which were
-created on start and not destroyed on stop.
-
