Jakub Kicinski	ea9b636201	samples: bpf: remove load_sock_ops in favour of bpftool ... bpftool can do all the things load_sock_ops used to do, and more. Point users to bpftool instead of maintaining this sample utility.

Lawrence Brakmo	03e982eed4	bpf: Fix tcp_clamp_kern.c sample program ... The program was returning -1 in some cases which is not allowed by the verifier any longer.

Lawrence Brakmo	6c4a01b278	bpf: Sample bpf program to set sndcwnd clamp ... Sample BPF program, tcp_clamp_kern.c, to demostrate the use of setting the sndcwnd clamp. This program assumes that if the first 5.5 bytes of the host's IPv6 addresses are the same, then the hosts are in the same datacenter and sets sndcwnd clamp to 100 packets, SYN and SYN-ACK RTOs to 10ms and send/receive buffer sizes to 150KB.
