bpf: sockmap sample test for bpf_msg_pull_data
This adds an option to test the msg_pull_data helper. This uses two options txmsg_start and txmsg_end to let the user specify start and end bytes to pull. The options can be used with txmsg_apply, txmsg_cork options as well as with any of the basic tests, txmsg, txmsg_redir and txmsg_drop (plus noisy variants) to run pull_data inline with those tests. By giving user direct control over the variables we can easily do negative testing as well as positive tests. Signed-off-by: John Fastabend <john.fastabend@gmail.com> Acked-by: David S.
