patch 'common/cnxk: remove VLA in interrupt configuration' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/23/26. 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/707bce0ae59f787289944b4ba8928cd79389d721

Thanks.

Kevin

[ upstream commit 1fb9f4ab14b34fe6b1613c1b37f84602654b77ce ]

This fixes errors when compiled with LTO about large VLA.
../drivers/common/cnxk/roc_platform.c: In function ‘irq_init’:
../drivers/common/cnxk/roc_platform.c:92:14: warning: argument to
	variable-length array is too large [-Wvla-larger-than=]
   92 |         char irq_set_buf[MSIX_IRQ_SET_BUF_LEN];
      |              ^

Since the number of IRQ is limited by EAL max interrupt vectors
use that define that already exists rather than a function call
hidden in a macro.

Bugzilla ID: 1863
Fixes: 375cb1601882 ("common/cnxk: move interrupt handling to platform-specific")
