Sorry, fix the typo. It should be "linux-6.17.y stable branch:", not 6.12.

Hi,

The following patch has already been merged into mainline (master) and the linux-6.17.y stable branch: net: lan743x: Allocate rings outside ZONE_DMA (commit 8a8f3f4991761a70834fe6719d09e9fd338a766e) https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...

I believe this patch should be backported. Our customer is experiencing an issue where a Microchip LAN7430 NIC fails to work in a crashkernel environment. Because the driver uses the ZONE_DMA flag, memory allocation fails when crashkernel reserves memory — preventing the card from functioning, especially when they try to transfer the VMcore file over network.

We are using older kernel versions and request that this fix be applied to the following branches: linux-6.1.y linux-6.6.y linux-6.12.y Could you please help backport this fix?

Thank you for your time and support.

Best regards, Liyin
