[LTP] [PATCH v3 3/9] tst_net.sh: Introduce TST_LIB_NET_LOADED

[Petr Vorel]

to load it only once.

Some tests (macsec0{1,2}.sh) load tst_net.sh twice via loading from
ipsec_lib.sh and virt_lib.sh. That brings duplicity in some variables
(TST_OPTS) and create infinite loop, as tst_net_setup calls itself.
