Bug#896165: linux: request packaging of bpftool

control: severity -1 important

Dear Maintainers,

I would like to add the packaging of a direct dependency to the list: libbpf.
This library is most useful for using currently ongoing extensions of the linux
kernel towards a new high-speed packet processing layer called XDP which uses
eBPF.

One software currently in Debian that might directly benefit from this library
is suricata (https://suricata.readthedocs.io/en/latest/capture-hardware/ebpf-
xdp.html).
Please consider to maybe include this library in your current endeavors to
allow us supporting this feature in the suricata package and future software to
come.

Thank you,
Robert Haist
