patch 'net/gve: increase range of DMA memzone IDs to 64 bits' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/04/26. 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/2522b2c686fe890674dec6d12175828105b95e62

Thanks.

Kevin

Subject: [PATCH] net/gve: increase range of DMA memzone IDs to 64 bits

[ upstream commit cfc0de855ff5483ae807901c0e2be1a4f30681ee ]

Long running programs can very easily eclipse this 16-bit range, leading
to name collisions and failed DMA region allocations despite there being
plenty of available memory.

Fixes: c9ba2caf6302 ("net/gve/base: add OS-specific implementation")
