My expectation is that every non-dodgy manufacturer of a network device would test the features they're developing. So, when (say) offloading support of some variety is newly added to a chip set, whoever is adding that support would be testing it at the full speed of the device. If the developers aren't verifying the things they're adding work (somehow), there's something wrong. :(
