From 106c35dda32f8b63f88cad7433f1b8bb0056958a Mon Sep 17 00:00:00 2001 From: Jiri Benc Date: Tue, 8 Oct 2019 15:10:45 +0200 Subject: selftests/bpf: More compatible nc options in test_lwt_ip_encap Out of the three nc implementations widely in use, at least two (BSD netcat and nmap-ncat) do not support -l combined with -s. Modify the nc invocation to be accepted by all of them.
