nit: I'd use empty string instead of zero.
testcases/lib/tst_net.sh
-export TST_NETLOAD_BINDTODEVICE="${TST_NETLOAD_BINDTODEVICE:-1}"
+export TST_NETLOAD_BINDTODEVICE="${TST_NETLOAD_BINDTODEVICE-1}"

testcases/network/mpls/mpls_lib.sh
-TST_NETLOAD_BINDTODEVICE=0
+TST_NETLOAD_BINDTODEVICE=

Kind regards,
Petr
