[dpdk-stable] patch 'ethdev: validate input in module EEPROM dump' has been queued to stable release 19.11.9

[Christian Ehrhardt <christian.ehrhardt@canonical.com>]

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/19/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/d50e609bde4d36b56e794701018c15d90027821a

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] ethdev: validate input in module EEPROM dump

[ upstream commit e2bd08d569d9821131d8e245446d24eaed145f21 ]

The validity verification of input parameters should be performed at
API layer, not in the PMD.

Fixes: 3a18c44b45df ("ethdev: add access to EEPROM")
Fixes: 40ff8b305ab8 ("net/e1000: add module EEPROM callbacks for e1000")
Fixes: f2088e785cca ("net/i40e: fix dereference before check when getting EEPROM")
Fixes: b74d0cd43e37 ("net/ixgbe: add module EEPROM callbacks for ixgbe")
Fixes: 8a6a09f853a0 ("net/mlx5: support reading module EEPROM data")
Fixes: 58f6f93c34c1 ("net/octeontx2: add module EEPROM dump")
