See #5087 for examples of how it can be used / how allocations can be removed entirely through thinking about a different approach without intermediate allocation of a vector.

You said QEMU provides this - how does it do it?

This seems a duplicate of #5431 (although reporting via balloon wouldn't require any agent to handle this.)

I think it is probably a reasonable to have some counters for when the rate limiter fires and rejects some ops/data. e.g. `rate_limiter_exceeded_bytes` and `rate_limiter_exceeded_ops` - whether they can help...

The PCIe capability structure contains has variable length capabilities where they are encoded as approximately (capability id, size of capability, offset to next capability). From this you can find the...

@liuw Can you further elaborate on the use case for this please?

@rveerama1 Thank you for opening the issue with crate upstream - I think we can wait to hear from them as to a possible solution.
