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.
