Did this issue preexist these commits:
b25b44cd178c ("selftests: drv-net: tso: fix non-tunneled tso6 test case 
name")
2cfbcc5d8af9 ("selftests: drv-net: tso: fix vxlan tunnel flags to get 
correct gso_type")
266b835e5e84 ("selftests: drv-net: tso: enable test cases based on 
hw_features")

or is this a possible regression?
