The BPF instruction set architecture is now RFC 9669

Description:
After a couple of years of effort, the BPF instruction set architecture has been accepted as RFC
9669 , giving it a standard outside of the in-kernel implementation. This message from David
Vernet (who also contributed an article on
the standardization process last year) describes the process and why it
is important: Though some vendors have already implemented BPF offloading
capabilities without having a standardized ISA, others are not
quite as risk tolerant. As Christoph [Hellwig] discussed at LSFMM
2022, certain NVMe vendors have expressed an interest in building
BPF offloading capabilities for various use cases such as eXpress
Resubmission Path (XRP), but they simply can't fund such a project
without certain components of BPF being standardized. Hence, the
effort to standardize BPF was born.
