[PATCH net-next 0/2] net: ntb_netdev: Preserve checksum offload across NTB

ntb_netdev may be used on embedded systems, where CPU resources are
often limited. L4 checksum calculation can therefore become a bottleneck
even when traffic stays within a trusted PCIe fabric.

This small series carries CHECKSUM_PARTIAL state across the NTB link
using opaque per-payload metadata in ntb_transport. Existing peers
continue to use software checksumming. The feature remains disabled by
default and must be enabled explicitly for trusted links.

Best regards,
Koichiro
