patch 'net/dpaa2: fix extract buffer preparation' has been queued to stable release 24.11.4

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/05/25. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/443b13ab4383fafc4934d93603e2d19a9ef5c69f

Thanks.

Kevin

Subject: [PATCH] net/dpaa2: fix extract buffer preparation

[ upstream commit 53bb620fa66ec89ee888573009771e0e9f279930 ]

1) The max size of extract buffer should be size of
   "struct dpni_ext_set_rx_tc_dist"(488), which is greater than 256.
2) dpkg_prepare_key_cfg is responsible to clear
   extract buffer before preparing.

Fixes: 25d0ae624245 ("net/dpaa2: check IOVA before sending MC command")
