[net-next,1/4] selftests: mptcp: set all env vars as local ones
Commit Message
From: Geliang Tang <geliang.tang@suse.com>
It would be better to move the declaration of all the env variables to
do_transfer(), run_tests(), or pm_nl_set_endpoint() as local variables,
instead of exporting them globally at the beginning of the file.
