by the verifier any longer.

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).
