-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.
-
