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 61bc4d8daa bpf: Sample bpf program to set SYN/SYN-ACK RTOs
The sample BPF program, tcp_synrto_kern.c, sets the SYN and SYN-ACK
RTOs to 10ms when both hosts are within the same datacenter (i.e.
small RTTs) in an environment where common IPv6 prefixes indicate
both hosts are in the same data center.
