Subject: [PATCH 0/1] Open source our TC classifier

We've been developing an in-house L4 load balancer based on XDP
and TC for a while. Following Alexei's call for more up-to-date examples of
production BPF in the kernel tree [1], Cloudflare is making this available
under dual GPL-2.0 or BSD 3-clause terms.

The code requires at least v5.3 to function correctly.
