I would have made the default for the MSI option to be true, but that is a 
matter of preference, and only experience would show which default leads to the 
fewer failures. On my laptop, both rtl8188ee and rtl8723be work either way. I am 
now working on a driver for the RTL8192EE that also can use MSI - that has only 
been tested with the option on.
