Hi Toke,
here is a target with lot of interest for it : www.gtp-guard.org
When dealing with mobile network data-plane, at some point you have
ordering issues and shaping needs, so queuing is truly needed.
Alternatively ones can implement PIFO or others built on AF_XDP but if
dedicated bpf map covers the use-case, would be nice.
Watching at your LPC 2022 presentation, at the end, discussions where
made around using existing Qdisc kernel framework and find
a way to share the path between XDP and netstack. Is it a target for
adding PIFO, or more generally getting queuing support for XDP ?
regs,
Alexandre
