I want to use eBPF to run packet inspection and capture on my NIC, but the library functions accessible from eBPF don't include access to a nanosecond-resolution clock counter, or to efficient DMA to host procesd memory, needed for the job. Is anybody working on that?

bpf_ktime_get_ns() returns nanoseconds, is it not adequate?

I can't really speak to the use of dma and memory, I haven't really looked at that.

Thank you, I don't recall finding this when I studied it last.
