From: Jiri Benc Date: Fri, 18 Oct 2019 12:00:42 +0000 (+0200) Subject: selftests/bpf: More compatible nc options in test_tc_edt X-Git-Tag: v5.4-rc6~8^2~47^2~5 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=11875ba7f251c52effb2b924e04c2ddefa9856ef;p=linux-block.git selftests/bpf: More compatible nc options in test_tc_edt 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.
