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	a4174f0560	bpf: Fix tcp_bufs_kern.c sample program ... The program was returning -1 in some cases which is not allowed by the verifier any longer.

Lawrence Brakmo	d9925368a6	bpf: Sample BPF program to set buffer sizes ... This patch contains a BPF program to set initial receive window to 40 packets and send and receive buffers to 1.5MB. This would usually be done after doing appropriate checks that indicate the hosts are far enough away (i.e. large RTT). Signed-off-by: Lawrence Brakmo <brakmo@fb.com> Signed-off-by: David S.
