Queue length and active flows meta data

["MD I. Islam" <tamim@xxxxxxxxxxx>]

Hi

I need to implement XCP[1] like protocol on data plane. To do this, I
need to know the queue length and the number of active flows. Is there
a way XDP or tc_cls exposes those information to eBPF program?

Thanks
Tamim
