l2_tos_ttl_inherit.sh verifies the inheritance of tos and ttl
for GRETAP, VXLAN and GENEVE.
Before testing it checks if the required module is available
and if not skips the tests accordingly.
Currently only GRETAP and VXLAN are tested because the GENEVE
module is missing.

Tested with:

This wakes up any waiters as if the event had been set, but does not set the

waiter is woken.
