# Apart from looking for netmap headers, we make sure that the host API version
# supports the netmap backend (>=11). The upper bound (15) is meant to simulate
# a minor/major version number. Minor new features will be marked with values up
# to 15, and if something happens that requires a change to the backend we will
# move above 15, submit the backend fixes and modify this two bounds.
