patch 'net/octeon_ep: handle interrupt enable failure' 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/4f3ad5beb3a4ef8c38d0a6fdc01f12a0f039f327

Thanks.

Kevin

[ upstream commit 0fcfecc1f1eb3d8b1e8632134462caf3b3885281 ]

Patch checks the return value of interrupt enable
and returns gracefully if file handler is not available.
