Workarounds in generic EHCI code

[Rafal Jaworowski]

Greetings,

I'd like to hear comments on the proper way of handling non-standard behaviour
of a host controller when a workaround needs to be aplied at the shared code
level. In the following I followed an example of existing VIA/ATI chip workaround:

http://people.freebsd.org/~raj/patches/misc/usb-workarounds.diff

The respective flags are potentially set in platform-specific attachment
driver code, which knows if they apply etc.

Does anybody see a better way to handle such cases?
