[ Upstream commit a17975992cc11588767175247ccaae1213a8b582 ]
Fix the way tcpdump is executed by: - Using the right variable for the namespace. Currently the use of the empty "ns" makes the command fail. - Waiting until it starts to capture to ensure the interesting traffic is caught on slow systems. - Using line-buffered output to ensure logs are available when the test is paused with "-p". Otherwise the last chunk of data might only be written when tcpdump is killed.
