OK, make sense, I'll put it just into tst_net_run().

Sorry, I was wrong. Previously I meant tst_rhost_run *without -s* option.

tst_rhost_run with -s option in cleanup is only in 2 files:
testcases/network/mpls/mpls_lib.sh
testcases/network/tcp_cmds/sendfile/sendfile01
Maybe that's a mistake (unlike C functions where error in SAFE_* continue with
warning, in shell it exits during cleanup).

Without -s we don't get any warning, which is often desirable.
=> I'll put warning and -q switch to suppress it only into tst_net_run().


Kind regards,
Petr
