[dpdk-stable] patch 'net/ice: fix memzone leak when firmware is missing' has been queued to stable release 20.11.3

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/14/21. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/6dd0f78f2c43f5fc5d1ddc58cc00be04c04121da

Thanks.

Luca Boccassi

Subject: [PATCH] net/ice: fix memzone leak when firmware is missing

[ upstream commit 850989f9381902e36d44c2c4c7409ad703ef99cb ]

Caught by our QE.
When the firmware is missing, memzones were not released.

With 20 tries attaching a net/ice port, we would end up with:

EAL: Probe PCI driver: net_ice (8086:159b) device: 0000:5e:00.0 (socket 0)
EAL: memzone_reserve_aligned_thread_unsafe(): Number of requested memzone
  segments exceeds RTE_MAX_MEMZONE
ice_dev_init(): Failed to initialize HW
