What about checking vti drivers in stress/ipsec/ipsec_lib.sh:tst_ipsec_setup_vti()
Similar to the checks for xfrm_user driver there...

For example:

tst_net_run -q "tst_check_drivers ip_vti ip6_vti" || \
    tst_brk TCONF "vti driver not available on lhost or rhost"


I think this should work for wireguard02 test as well.
