Another OS use interface numbers to match the driver and interface. It seems these devices are designed with that in mind - using static interface numbers for the different functions. This adds support for matching against the bInterfaceNumber, allowing such devices to be supported without having to resort to testing against interface number whitelists and/or blacklists in the probe.

As localmodconfig is conservative and tries to make the minimum config without breaking the user's kernel, or keeping the user from using devices that were loaded when the lsmod was done, all modules that select this module will also be enabled. If you needed module A, but module A did not have a prompt but needed module B to be selected, localmodconfig would make sure B was still enabled. If not only B selected A, but C, D, E, F, and G also selected A, then all of those would also be included, as well as the modules they depend on. This ballooned the number of configs that localmodconfig would keep. The fix here is to process the depends first, and then record those configs that did not have a prompt and needed to be selected. After the depends are done, check what configs are needed to select the configs in the list, and if a config that selects it is already set, then we don't need to do anything else. If no config that selects the config is set, then just pick one and try again. This change brought down the number of selected modules from 290 to 67! Both before and after were run against a config that had 3095 modules enabled.

It doesn't set new symbols to 'n', but instead sets it to their default values. Unfortunately, assuming that it actually did this, broke ktest in some of its tests. For example, the tests to create a minimum config and even a config bisect, depends on removing various configs and using oldnoconfig to get rid of other configs that may have depended on it. But because some configs that it was trying to disable, were in fact default enabled, this caused those configs to re-enable and corrupt the test. I thought about fixing oldnoconfig, but I'm afraid that people are already dependent on its current behavior. Instead, I'm just updating the documentation to state that it sets the new symbols to their default values and not to 'n'. Ideally, this would be called, 'olddefconfig' and we have an 'oldnoconfig' that actually disables the new symbols. But it's useless for me now. If it changed, ktest would need to be consistent between each version, and that would be to difficult to detect. I'll handle this issue with ktest with other means.
