// TODO: If we're certain we want case-insensitive name comparison, please document the rationale.
// Windows requires each interface to have a different name. When
// enforcing this, Windows treats interface names case-insensitive. If an
// interface "FooBar" exists and this function reports there is no
// interface "foobar", an attempt to create a new interface and name it
// "foobar" would cause conflict with "FooBar".

// Iterate.
