XRP is a regular BPF hook in Linux and requires no additional standardization. The device never "calls out to BPF programs in the driver" - it generates a normal completion interrupt and Linux runs a BPF hook in the completion path. This is no different than other kernel BPF hooks elsewhere and doesn't provide any additional reason or need to standardize BPF.

The article misstated that XRP was a framework used for offloading BPF programs to NVMe devices. That's not correct, and XRP is not one of the emerging use cases for BPF that is driving standardization.
