i40iw is one of the drivers that doesn't do ABI versions right, so
this is all meaningless. You should probably fix it:
static const struct verbs_device_ops i40iw_udev_ops = {
.name = "i40iw",
.match_min_abi_version = 0,
.match_max_abi_version = INT_MAX,
0 and INT_MAX need to be something sensible.

travis does the tests.
